DeWalt DWE402
Best OverallPros
- Powerful 11-amp motor handles tough masonry cuts
- Dust ejection system prevents debris from entering tool
- Compact and lightweight for overhead work
Cons
- No paddle switch (slide switch only)
- Corded only limits mobility on large sites
The DeWalt DWE402 is a 4.5-inch angle grinder built for continuous use on masonry. Its 11-amp motor delivers 11,000 RPM, which is ideal for cutting brick and block with a diamond blade. The dust ejection system is a key feature for masonry work, as it pushes debris away from the motor and switch, extending the tool's life on dusty job sites.
Owner reviews consistently praise its power-to-weight ratio and durability. Many users report using it for years on professional construction sites without issues. The slide switch is a personal preference, but for masonry cutting where you often need constant-on operation, it works well.
Makita XAG04Z
Best CordlessPros
- Brushless motor for longer run time
- Automatic speed control under load
- Accepts all Makita 18V batteries
Cons
- Battery and charger sold separately
- Slower RPM than corded models for deep cuts
The Makita XAG04Z is a top cordless choice for masonry work. It uses an 18V brushless motor with automatic speed control, which maintains RPM under load when cutting through dense brick or paver. The tool is part of Makita's 18V LXT ecosystem, so it shares batteries with over 300 other tools.
Owner reviews highlight the XAG04Z's balance and power for a cordless unit. It is best for light to medium masonry tasks like cutting a few bricks or scoring stone. For all-day cutting, you will need multiple batteries, but the run time per 5.0Ah pack is solid for intermittent use.
Bosch 1375A
Best Budget CordedPros
- Very lightweight and easy to handle
- Low price point for occasional use
- Includes two wrenches and side handle
Cons
- 6-amp motor bogs down on thick masonry
- No dust protection system
The Bosch 1375A is a compact and affordable 4.5-inch angle grinder suitable for light masonry work. It spins at 11,000 RPM but only has a 6.0-amp motor, so it is best for scoring brick or cutting thin pavers rather than deep block cuts. Its lightweight design (3.75 lbs) makes it easy to use one-handed for short tasks.
Owner reviews appreciate the low cost and reliability for DIY projects. Many users buy this as a backup grinder or for occasional masonry work. The lack of dust protection means you should clean it regularly after masonry use, but for the price, it is a solid entry-level tool.
Milwaukee 2780-20
Best Heavy-Duty CordlessPros
- Powerful brushless motor with high torque
- REDLINK intelligence prevents overheating
- Accepts up to 5-inch discs
Cons
- Heavier than corded alternatives
- Battery and charger sold separately
The Milwaukee 2780-20 is a beast of a cordless grinder, built for heavy masonry work. Its M18 brushless motor delivers high torque at 9,000 RPM, and the REDLINK intelligence system protects the tool from overload and overheating. It can accept both 4.5-inch and 5-inch discs, giving you flexibility for deeper cuts.
Owner reviews praise its power, often comparing it to corded models. It is heavier than the Makita XAG04Z, but the trade-off is more cutting force for thick block or stone. This grinder is best for professionals who need cordless freedom without sacrificing performance on masonry.
Ryobi P423
Best DIY CordlessPros
- Affordable entry into cordless grinding
- Part of Ryobi ONE+ ecosystem
- Spindle lock for easy disc changes
Cons
- Brushed motor has less power and run time
- Not suitable for heavy or continuous masonry cuts
The Ryobi P423 is a budget-friendly cordless angle grinder for DIY masonry projects. It runs on Ryobi's 18V ONE+ battery system, which is common among homeowners. The 8,500 RPM brushed motor is adequate for cutting brick veneer, thin pavers, or scoring stone for landscaping projects.
Owner reviews note that it is a good grinder for the price, especially if you already own Ryobi batteries. It is not intended for professional or heavy use, as the motor can bog down on thick block. For occasional masonry work around the house, it offers good value and convenience without a cord.
What to Look for in an Angle Grinder for Masonry
When choosing an angle grinder for masonry, focus on power, speed, and dust protection. A higher amp rating (10+ amps for corded) or a brushless motor (for cordless) ensures the tool does not stall on dense materials. Look for a no-load speed of at least 8,500 RPM, as this is the minimum for effective cutting with diamond blades.
Dust protection is critical for masonry work. Tools with sealed bearings, dust ejection systems, or brushless motors last longer in dusty environments. Also consider the disc size: 4.5-inch grinders are standard, but 5-inch models offer deeper cuts. Finally, check the switch type: paddle switches offer better safety, while slide switches are easier for constant-on use.
Mistakes to Avoid When Cutting Masonry
One common mistake is using the wrong blade. Always use a diamond-tipped blade rated for masonry, not a grinding wheel. Another error is applying too much pressure: let the grinder's weight and speed do the work. Pushing hard can overheat the blade and stall the motor.
Do not skip dust protection. Masonry dust is abrasive and can destroy a grinder's motor and switch quickly. Use a grinder with dust ejection or sealed bearings, and clean the tool after each use. Finally, avoid using a cordless grinder with a small battery for heavy cuts. Use at least a 4.0Ah or larger battery for masonry work.
What to Check Before Buying
Before buying, check the motor type: brushless motors are more efficient and last longer than brushed motors, especially for cordless models. For corded grinders, look for a high amp rating and a durable gear case. Also verify the arbor size: most 4.5-inch grinders use a 5/8-inch arbor, but some budget models use M14 or other sizes.
Check the warranty and brand reliability. DeWalt, Makita, Bosch, and Milwaukee offer strong warranties and have proven track records for masonry tools. Finally, consider the battery ecosystem if going cordless. Sticking with one brand for all your tools saves money on batteries and chargers.

A 4.5-inch angle grinder is the most common and versatile size for masonry cutting. A 5-inch model offers deeper cuts.
Do I need a dust collection system for masonry grinding?
Dust collection is highly recommended for health and tool longevity. Many grinders have dust ejection ports for connecting a vacuum.
How long do diamond blades last on masonry?
A quality diamond blade can last for hundreds of cuts in brick or block. Blade life depends on material hardness and cutting technique.
Can I use a masonry blade on a grinder for metal?
No, masonry blades are not designed for metal. Use a separate grinder or change the blade to avoid cross-contamination and safety risks.
What safety gear do I need for masonry cutting?
Always wear safety glasses, a dust mask or respirator, hearing protection, and heavy gloves. Masonry dust contains silica, which is harmful.
Is a paddle switch better than a slide switch for masonry?
A paddle switch offers better safety because it requires constant pressure. However, a slide switch is easier for long, continuous cuts.
