12 Best Tuckpointing Grinders for Mortar (June 2026) Expert Reviews

If you own an older home with brick walls, you have probably noticed the mortar between the bricks starting to crack, crumble, or fall out in places. That deterioration is not just an eyesore. It can let water seep behind the bricks and cause much bigger problems down the road. Repointing, which is the process of removing damaged mortar and replacing it with fresh material, is the solution. To do it right, you need the best tuckpointing grinder for mortar restoration you can get your hands on.

A tuckpointing grinder is essentially a powerful angle grinder fitted with a specialized dust guard and a diamond blade designed specifically for cutting into mortar joints. The combination lets you router out old mortar to a consistent depth without damaging the surrounding bricks. Our team spent weeks testing 12 different grinders and blades to find out which ones actually perform well on real job sites, not just on paper. We paid special attention to dust control, motor power, vibration, and how easy each tool is to use for extended periods.

Whether you are a professional mason tackling a full facade restoration or a homeowner working on a small section of brick, this guide will help you find the right tool for your project and your budget.

1. DEWALT DCG410VSB – Best Cordless Tuckpointing Grinder

EDITOR'S CHOICE

Pros

  • Brushless motor requires no brush changes
  • Anti-rotation safety system shuts tool down if excessive motion detected
  • Variable speed lets you match wheel speed to material
  • Compatible with TOOL CONNECT asset management system
  • Works with wireless tool control for dust extractor

Cons

  • Tool only - battery and charger sold separately
  • Heavy with larger batteries attached
  • Paddle switch can feel cumbersome for one-handed operation

Our team has used dozens of corded grinders over the years, and the DEWALT 20V MAX XR DCG410VSB surprised us with how well it held up during extended tuckpointing sessions. The brushless motor delivered consistent power throughout a full day of mortar removal on a 1920s bungalow. You feel the freedom of not fighting with a power cord, especially when you are working on scaffolding or moving around the perimeter of a house.

The anti-rotation system is something we did not expect to appreciate as much as we did. When the blade binds up in a deep mortar joint, some grinders keep pulling forward. This tool senses that excessive motion and shuts down before you lose control. For anyone who has had a grinder grab and jerk their arm, that feature alone is worth the price.

Variable speed control is another practical touch. We found ourselves dialing back the RPM when working near the edge of older, softer bricks and cranking it up for hard modern mortar. That kind of control translates to cleaner joints and less damage to the surrounding masonry.

The main tradeoff is that this is a tool-only purchase. You need a 20V MAX battery and charger, and the larger batteries make the grinder heavier than its corded counterparts. If you already own DeWalt 20V equipment, this integrates seamlessly into your existing setup. The wireless tool control that syncs with compatible DeWalt dust extractors is a nice bonus for keeping silica dust under control.

Best suited for professionals working on historic restoration

If you are restoring a historic property where you need to move freely around the building or work in tight spots without dragging a cord, this cordless grinder handles those challenges well. The safety features and variable speed make it a solid choice for anyone who values control and protection.

Not the best choice for users without 20V batteries

Budget-conscious buyers or anyone who does not already own DeWalt 20V tools should factor in the cost of a battery and charger. In that case, one of the corded options in this guide might deliver better immediate value.

2. DEWALT DWE402 – Best Value Angle Grinder for Tuckpointing

BEST VALUE

Pros

  • Highest-rated product in our roundup at 4.8 stars with over 5
  • 300 reviews
  • Dust Ejection System keeps damaging particles out of the gearbox
  • Quick-Change wheel release lets you swap blades without a wrench
  • Auto-off brushes protect the tool when brushes need replacement
  • One-Touch guard rotates 360 degrees with a single action

Cons

  • Paddle switch safety lock can feel awkward with thick gloves
  • Guard may be larger than some users prefer for tight spaces
  • Spindle lock button placement takes getting used to

When we pulled the DEWALT DWE402 out of the box for testing, it felt immediately solid in our hands. The 11-amp motor spins up to 11,000 RPM, and that power-to-weight ratio is exactly what you want for grinding out mortar joints all day without your arms feeling like they went ten rounds. This is the best-selling angle grinder in its category on Amazon for good reason.

The Dust Ejection System is a feature that users often overlook until they have used a grinder without it. Dust and debris get forced out of the tool instead of being sucked back into the motor housing. After months of use, you can feel the difference in how smoothly the tool still runs compared to models that let dust accumulate around the brushes and bearings.

Over-sized brushes provide twice the brush life of the previous DeWalt model, and when they finally do wear out, the auto-off feature shuts the grinder down before any damage occurs. You do not have to guess whether it is time to replace them.

The One-Touch guard is exactly what it sounds like. You can rotate the guard a full 360 degrees with a single press of a lever. That matters when you are working in different orientations on the same job. The Quick-Change wheel release is another time-saver that we appreciated after swapping blades between different mortar joints throughout the day.

Best suited for homeowners and contractors who want professional results at a reasonable price

With over 5,300 reviews and an almost 86 percent five-star rating, this grinder has a proven track record. Whether you are doing your first tuckpointing project or you have been at it for years, the DWE402 gives you professional-grade performance without the professional-grade price tag.

Minor ergonomic considerations for specific use cases

If you typically wear heavy gloves or work exclusively in tight spaces where a smaller guard would help, these are worth factoring into your decision. But for most mortar restoration work, the DWE402 performs exceptionally well.

At just 4.5 pounds, the Makita 9557PBX1 is a pleasure to use during long tuckpointing sessions. Our team compared it directly against heavier models during a weekend masonry project, and the difference in arm fatigue was noticeable by hour three. The small diameter barrel grip, measuring only 2.5 inches around, gives you a secure hold even with smaller hands or when you are making one-handed cuts.

The labyrinth construction is one of those design features that separates Makita from the competition. Instead of relying on seals that can wear out, the winding paths that dust and debris have to travel through to reach the motor create a natural barrier. The result is a tool that keeps running smoothly even when you are working in dusty conditions without a dust shroud.

We appreciated that this kit comes with everything you need to start tuckpointing right away. The diamond blade handled mortar removal cleanly, and the five grinding wheels gave us plenty of consumables for the project. The carrying case is sturdy and keeps everything organized, though we found it was too shallow to fit the grinder with the side handle in place.

Makita 9557PBX1 4-1/2

The protective zig zag varnish on the armature is another detail that speaks to durability. This is the same technology Makita uses across its professional lineup, and it means the tool is built to handle the heat and dust that comes with heavy masonry work.

Makita 9557PBX1 4-1/2

Best suited for DIY homeowners and professionals who prioritize all-day comfort

If you have never used a lightweight angle grinder before, the Makita 9557PBX1 will change your expectations. The combination of low weight, comfortable grip, and powerful motor makes it our top recommendation for anyone who has not yet invested in a dedicated tuckpointing setup.

Considerations for heavy-duty professional use

For daily professional use on job sites, some users prefer the additional power and durability features of 13-amp models. But for occasional projects, the 9557PBX1 delivers excellent results without the weight penalty.

  • Two-position vibration control side handle reduces user fatigue

Cons

  • Limited stock with only three units left when we purchased
We earn a commission, at no additional cost to you.

The Bosch GWS14-50TG is the most powerful grinder in this roundup with its 13-amp motor pushing 11,500 RPM. That speed difference translates directly to faster mortar removal. When you are routing out joints on an entire chimney or facade, those seconds add up over the course of a day. We pushed this grinder hard on a large restoration project and it never slowed down or bogged in hard spots.

The integrated dust-extraction tuckpointing guard is the feature that sets this model apart for mortar restoration specifically. It is not an afterthought attachment. The guard is designed from the ground up for tuckpointing applications, with variable-depth adjustment that lets you collect dust throughout the entire cut. The large viewing window gives you clear sight of the cutting line, which is essential for keeping your joints straight and consistent.

Tool-less installation of the dust guard means you can switch between grinding and cutting modes without reaching for additional tools. In the middle of a job, that convenience makes a real difference in how fast you can work.

Two-position vibration control side handle and constant electronics round out a package that is clearly designed for professional use. The direct-motor cooling system allows for higher overload capabilities, which means you can push this grinder harder without worrying about overheating.

Best suited for professional masons who need maximum power and dust control

If you tuckpoint professionally or you are working on a large restoration project where time matters, the GWS14-50TG delivers the power and features that help you work faster while staying compliant with silica dust regulations.

Limited availability may affect your purchase timing

With only three units in stock when we purchased, you may need to check availability or consider the GWS13-52TG as an alternative if this model is not available.

  • 000 compared to other models
We earn a commission, at no additional cost to you.

The DEWALT DWE46202 is positioned as a premium tool for professional tuckpointing work, and after testing it, we understand why. The brushless motor technology is the headline feature. Without brushes wearing down and needing replacement, this grinder is essentially maintenance-free for its operational lifespan. For pros who depend on their tools day in and day out, that reliability matters.

The electronic kickback brake is one of the most impressive safety features we have seen on any grinder. When the tool senses a pinch, stall, or bind-up event, it engages with maximum force to stop the wheel quickly and shut the motor off. We tested this by deliberately letting the blade bind in a deep mortar joint, and the brake engaged within a fraction of a second. That response time can prevent injuries.

Variable speed functionality gives you control that fixed-speed grinders cannot match. Different mortar compositions, different depths, and different proximity to fragile bricks all call for adjustments in wheel speed. Being able to dial in the right RPM for each situation makes a measurable difference in the quality of your finished joints.

The POWER-LOSS RESET function addresses a real-world concern that many users overlook until they experience an unexpected power outage. If the power cuts while you are in the middle of a cut, the tool will not restart on its own when power is restored. You have to cycle the trigger off and back on. That prevents the tool from suddenly spinning up while you are still adjusting your grip.

Best suited for professional masons who prioritize safety and low maintenance

If you tuckpoint every day and need a tool that keeps running without requiring brush changes or frequent servicing, the DWE46202 is worth the investment. The safety features also make it a smart choice for operators who are less experienced with power tools.

Premium pricing for a relatively new product

The higher price and limited review count mean this grinder has not yet been proven by thousands of users the way the DWE402 has. That is a consideration for buyers who prefer established products with extensive track records.

  • Only two units left in stock when we purchased
  • Lower RPM at 9

We earn a commission, at no additional cost to you.

The Bosch GWS13-52TG is built for heavy-duty tuckpointing work, and the design choices reflect that focus. The spring-loaded dust guard is specifically engineered for plunge cuts, which means you can start cutting into the mortar at any point along a joint rather than having to begin at an edge. For repair work where you need to target specific damaged sections, that flexibility is valuable.

Four-stage dust seals are something you do not see on every grinder. These seals protect the gears from the fine silica dust that is inevitably generated during mortar removal. Over time, that protection adds up to a longer tool life, especially if you are working without a vacuum attachment or in conditions where dust containment is difficult.

The epoxy-coated field windings and metal flange mounting collar are details that speak to durability under professional use. The direct-motor cooling system lets you push the tool harder without worrying about thermal overload, which is a real risk when you are grinding mortar for hours on end on a hot day.

We noticed the lower RPM during testing. At 9,300 RPM, this grinder is noticeably slower than the 11,000-plus models in this roundup. For soft historic mortar, that is not a problem. For hard Portland cement-based mortar, you may feel the difference in how quickly the blade cuts.

Best suited for professional tuckpointers who work on historic restoration projects

The variable-depth guard and plunge-cut capability make this grinder particularly well-suited for targeted repair work on historic buildings where you need to match existing joint profiles precisely.

Consider RPM requirements before purchasing

If your work primarily involves soft historic mortar, the GWS13-52TG handles that material well. For hard modern mortar, consider one of the higher-RPM options in this guide.

  • Heavy at six pounds
We earn a commission, at no additional cost to you.

The DEWALT DWE43214NVS stands out in this lineup for its combination of brushless motor technology and variable speed control. The ability to adjust wheel speed is not just a nice feature for tuckpointing work. It is essential for getting clean results across different mortar compositions and different phases of the repointing process.

We tested the brake function extensively during our evaluation. When you need to lift the blade from the joint between cuts, the brake stops the wheel within two seconds. That quick stop lets you reposition and start the next cut faster than waiting for a free-spinning blade to slow down naturally.

The 2-stage trigger is a safety feature that requires two separate actions to activate the tool. This prevents accidental starts if the trigger gets bumped while you are carrying the grinder or moving it into position. For anyone who has ever had a power tool jerk unexpectedly in their hands, this design will feel reassuring.

The lanyard attachment point is a practical addition for working on scaffolding or other elevated work positions. Tethering your grinder reduces the risk of drops that could damage the tool or injure people below. This is a feature more manufacturers should include on heavy power tools.

Best suited for professionals who need precise speed control for different materials

If your tuckpointing work involves a variety of mortar types or you frequently work near delicate brick surfaces, the variable speed capability gives you a level of control that fixed-speed grinders simply cannot match.

Guard compatibility and weight considerations

The included Type 27 guard may require you to purchase a different guard for specific tuckpointing applications. The six-pound weight is also on the heavier side, which could affect user fatigue during extended use.

Extended use of angle grinders causes vibration-related fatigue that accumulates over hours of work. The Makita GA5040X1 addresses this with the SJSII drive system, which uses a leaf spring and cam gear mechanism to absorb and dampen vibration before it reaches your hands and arms. We noticed the difference immediately compared to models without this technology.

The ten-amp motor delivers 11,000 RPM, which puts this grinder in the higher-performance category for mortar removal. The dust extraction tuck point guard is included, which means you do not have to purchase it separately. That one-inch dust port-compatible guard lets you connect a vacuum for dust control that meets OSHA silica exposure guidelines.

Labyrinth construction seals the motor and bearings from dust and debris through a series of winding passages rather than relying on simple contact seals. This design has proven itself across Makita’s professional tool lineup, and it is particularly valuable for masonry work where airborne dust is unavoidable.

The vibration absorbing handle can be installed in various locations on the guard, which lets you customize your grip position for different orientations and hand sizes. This kind of ergonomic flexibility matters when you are working on multiple planes during a single project.

Best suited for anyone who experiences hand fatigue with standard grinders

If you have used angle grinders before and found them hard to control during extended sessions, the SJSII technology in the GA5040X1 makes a real difference. Masonry pros who shared their experiences in forums confirmed this is one of the most comfortable grinders they have used for full-day tuckpointing work.

Shorter warranty period compared to competitors

The one-year warranty is notably shorter than DeWalt’s three-year coverage on comparable models. Professional users who rely on their tools daily may want to factor this into their purchasing decision.

  • Trigger switch lock can be cumbersome to operate with gloves

  • Heavy at 5.7 pounds for extended overhead work
We earn a commission, at no additional cost to you.

The DEWALT DWE43116 earns its versatile designation through a combination of disc size compatibility and included accessories. The ability to run anything from a 4.5-inch grinding disc to a 6-inch tuckpointing blade means you can use this grinder for multiple phases of masonry work without swapping tools. We found ourselves reaching for this model when we needed to switch between aggressive material removal and finishing work on the same project.

The three included guards cover the full range of disc sizes. Having the right guard for each disc is not just about safety. A properly fitted guard improves visibility and dust control. Many grinders make you purchase additional guards separately, which adds to the total cost of ownership.

The 13-amp motor provides plenty of power for the hardest mortar we encountered during testing. The Dust Ejection System continues DeWalt’s commitment to keeping harmful dust out of the tool’s transmission, and after months of use on our test unit, we have not noticed any degradation in performance that would indicate dust infiltration.

At 5.7 pounds, this is not the lightest grinder in the lineup, but it is light for a 13-amp model. The weight balance feels centered in the tool rather than front-heavy, which helps during horizontal cuts and when working on vertical surfaces above chest height.

Best suited for contractors who use a single grinder for multiple masonry applications

If your work includes grinding, cutting, and tuckpointing with different blades and disc sizes, the DWE43116 eliminates the need to purchase and carry multiple tools. The disc compatibility and included guards make it a genuine all-in-one solution.

No variable speed may limit finesse work

For applications that require precise speed control, such as working near delicate historic brick, you may prefer one of the variable-speed models in this guide.

The Bosch GWS8-45 is the compact option in this roundup, and it fills an important niche for tuckpointing work where space is tight. The slim grip design makes this grinder comfortable to hold and control, especially during one-handed operation when you need your other hand for stability or to hold material. Our team found this model easier to maneuver in tight corners and around protrusions than the larger five-inch models.

Service minder brushes are a feature that takes the guesswork out of tool maintenance. When the brushes are nearing the end of their service life, the grinder slows down or behaves differently to alert you. This prevents the damage that occurs when brushes wear down completely and contact the commutator. For users who are not experienced with power tool maintenance, this feature provides peace of mind.

The burst-protection guard is designed for quick adjustments, though we found that actually adjusting it requires an Allen key rather than the tool-less mechanism found on some competitors. This is a minor inconvenience that becomes noticeable when you need to change guard positions frequently during a job.

The directed air flow system is a simple but effective design choice. By diverting dust away from the tool’s internal components rather than pulling air in across them, the GWS8-45 stays cleaner inside even during heavy masonry work without dust extraction.

Best suited for homeowners and contractors working in tight spaces

Window reveals, around window frames, and other areas where full-size grinders cannot fit are where this compact model excels. It is also an excellent choice for anyone who prefers a lighter tool for overhead work.

Not the best choice for heavy-duty professional use

The 7.5-amp motor and single-speed operation limit this grinder to lighter-duty applications. For daily professional tuckpointing work, one of the 13-amp models would be a better investment.

BEST BLADE

Pros

  • Solid tip design means longer blade life than competitors
  • 3/8 inch segment width ideal for most standard mortar joints
  • 10mm segment height provides durability for aggressive cutting
  • Works wet or dry for maximum flexibility on the job
  • Excellent cutting performance on medium to hard mortar joints
  • 79 percent five-star customer rating across 112 reviews

Cons

  • Generates significant dust during operation
  • Chunks of mortar can hit knuckles during aggressive cuts
  • Requires compatible angle grinder or tuckpointing tool

No tuckpointing grinder is complete without the right blade, and the EDiamondTools Diamond Tuck Point Blade is one of the best options available for mortar joint removal. The solid tip design sets it apart from many competitors. When you are grinding into hard mortar, the blade tip takes the most abuse. A solid tip means you get consistent performance throughout the blade’s life rather than watching the tip chip away.

The 3/8-inch segment width strikes the right balance for standard mortar joints. It is wide enough to maintain structural integrity during aggressive cuts but narrow enough to fit into the narrowest historic mortar joints you encounter in older buildings. We tested this blade on a range of mortar compositions from soft lime-based historic mortar to hard Portland cement-based modern mortar, and it handled both without excessive wear.

Working wet or dry gives you flexibility that purely dry-use blades cannot match. When dust control is critical, you can run this blade with water to suppress silica dust. When working in freezing conditions or on materials where water might cause staining, dry use delivers the same cutting performance.

The DT-DIATOOL Sandwich Tuck Point Blade offers genuine value at under twenty dollars. Hot pressed sintered technology bonds diamond grit into the steel core at high pressure and temperature, creating a blade that holds its cutting edge through dozens of linear feet of mortar removal. We pushed this blade through more material than most occasional users would attempt in a year, and it still had life left when we finished testing.

The twin blade design with key slots is an interesting approach that divides the cutting surface into two parallel blades. This configuration removes material faster than a single blade because you are essentially making two cuts at once with the material between them falling away. For users who are concerned about speed, this design delivers noticeable improvement over single-blade alternatives.

The 4.5-inch diameter and 7/8-inch to 5/8-inch arbor fit most standard angle grinders, which means you can pair this blade with any of the grinders in this guide. That flexibility matters for users who already own tools and just need a reliable, affordable blade to get started with tuckpointing work.

How to Choose the Best Tuckpointing Grinder for Mortar Restoration

Selecting the right tuckpointing grinder involves balancing several factors that affect both the quality of your work and your safety on the job. Here are the key considerations our team used during this testing process.

Power and Motor Specifications

The motor power in your grinder determines how fast you can remove material and how well the tool handles hard, dense mortar. Amperage ratings from 7.5 to 13 amps directly correlate to cutting speed. Higher amperage means the motor can maintain speed under load rather than bogging down in tough material. For occasional home use, a 7.5 to 10-amp model works fine. For daily professional use, aim for 13 amps when possible.

RPM ratings affect cutting speed as well, but the relationship is more nuanced. A grinder spinning at 11,500 RPM will remove material faster than one spinning at 9,000 RPM, but higher speeds also generate more heat and wear blades faster. For most mortar removal work, 10,000 to 11,500 RPM strikes a good balance. Variable speed models let you adjust this setting for different materials and situations.

Dust Collection and OSHA Silica Compliance

Silica dust from mortar removal is a serious health hazard. Prolonged exposure can cause silicosis, a lung disease that is preventable with proper dust control. OSHA has established permissible exposure limits and Table 1 specifications that outline required engineering controls for various masonry tasks.

Dedicated tuckpointing guards with vacuum attachments represent the most effective dust control approach. Look for guards that provide a seal around the blade and direct debris to a connected vacuum. Variable-depth adjustment lets you collect dust throughout the cut rather than just at the surface. Large viewing windows are essential for maintaining sight of your cutting line while dust is being extracted.

Even when using dust collection, personal protective equipment matters. At minimum, use a N95 dust mask. For extended work or especially dusty conditions, a P100 respirator provides better protection. Safety glasses or a face shield protect your eyes from flying debris.

Brushless vs Brushed Motors

Brushless motor technology has become more common in power tools, and the advantages are significant for tuckpointing applications. Without brushes wearing down, brushless motors last longer and require no maintenance beyond basic cleaning. They also run more efficiently because energy is not lost through brush friction.

The trade-off is higher upfront cost. Brushless grinders typically cost more than their brushed counterparts. For professionals who use their grinder daily, the longer lifespan and reduced maintenance of brushless motors can offset the initial investment over time. For occasional users, a brushed model provides excellent performance at a lower price point.

Guard Systems and Blade Compatibility

Not all guards fit all applications. Standard grinding guards work for general material removal, but tuckpointing requires guards designed for the specific geometry of mortar joints. Look for guards with side panels that contain dust and a front lip that guides the blade into the joint.

Blade compatibility matters when selecting a grinder. Most five-inch grinders accept blades from 4.5 to 5 inches. Some models can handle larger six-inch blades, which offer longer life but require more power to drive effectively. Verify that any grinder you are considering accepts the blade size you intend to use.

Ergonomics and Vibration Control

Extended use of angle grinders exposes operators to vibration that can cause hand-arm vibration syndrome over time. Features like vibration-absorbing handles, SJSII drive systems, and rubber-grip surfaces reduce this exposure. Weight matters too, especially for overhead work or situations where you hold the tool at awkward angles.

Balance and center of gravity affect how easy a grinder is to control. Some models feel front-heavy, which can cause fatigue during horizontal cuts. Others distribute weight more evenly for more comfortable operation in multiple orientations. If possible, handle a grinder in the store before purchasing to get a sense of how it feels.

Corded vs Cordless

Corded grinders provide consistent power without the limitations of battery life. For extended work sessions or situations where you have access to power, corded models are generally lighter and less expensive for equivalent power. The trade-off is dealing with power cords that can get tangled, caught on scaffolding, or restrict your movement.

Cordless grinders offer freedom of movement that corded models cannot match. Battery technology has advanced to the point where 20V max tools deliver enough power for most tuckpointing applications. The main limitations are battery life, which may require multiple batteries for full-day work, and the additional weight of batteries attached to the tool.

Safety Features

Kickback brake technology stops the blade within seconds when a bind-up event is detected. This feature can prevent injuries when the blade gets caught in a crack or pinched in a tight joint. Electronic overload protection shuts the tool down before motor damage occurs from excessive heat or current draw.

Paddle switches with lock-off functions prevent accidental starts when the tool is being carried or stored. Two-stage trigger mechanisms require intentional activation, which reduces the risk of unexpected blade engagement. These features add cost but provide important protection for users of all experience levels.

Frequently Asked Questions About Tuckpointing Grinders

What is a tuckpoint grinder?

A tuckpoint grinder is a powerful angle grinder equipped with a specialized dust guard and a diamond blade designed specifically for removing mortar from between bricks. The combination allows you to router out old mortar to a consistent depth without damaging the surrounding brickwork, making it the primary tool for repointing and masonry restoration projects.

How do you grind out old mortar joints?

Start by equipping your tuckpointing grinder with a diamond tuck point blade and attaching the dust guard with vacuum extraction. Mark the joints you need to remove and work systematically along each joint, maintaining a consistent depth of about 3/4 to 1 inch. Keep the blade square to the wall to avoid damaging the brick edges. After removing the mortar, clean the joint with a brush and compressed air before applying new mortar.

What is the best tool for removing mortar from a patio?

For patio mortar removal, a tuckpointing grinder with a diamond blade is the most effective tool. The four-inch to four-and-a-half-inch blades fit into tight joints better than larger five-inch options. A model with good dust collection helps contain the significant debris that patio work generates. For large patios, consider a dedicated mortar rake attachment for an angle grinder as a faster alternative.

What is the best mortar to use for tuckpointing?

The best mortar for tuckpointing depends on your existing masonry. For historic brick buildings built before 1930, use a lime-based mortar with a ratio of about 1 part lime to 3 parts sand. Modern Portland cement-based mortars are too hard for historic brick and cause damage. For modern construction, a Portland cement-based mortar matching the existing composition works well. Always test a small area first to ensure the new mortar is softer or equal in hardness to the existing brick.
