The DeWalt DCG405B 20V MAX XR Angle Grinder is one of DeWalt's newest models and it features a brushless motor that eliminates the need to replace motor maintenance brushes. Other advantages of brushless motors include faster spin-up times and longer motor life than conventional brushed motors. The grinder is equipped with DeWalt's Kickback Brake safety system, which stops the grinding wheel in two seconds if the tool is pinched or jammed.

If the tool is running and loses power due to a blown fuse or accidental unplugging, the power loss reset feature will prevent the tool from being turned on again. The DeWalt DCG405B 20V MAX XR Angle Grinder won't cut power to it or grab your boot laces if the switch is on when you plug it in. A power-off reset prevents it from turning on again until it's unplugged and toggled to the "off" position.

The DeWalt DCG405B 20V MAX XR angle grinder can be power hungry, with some users reporting up to 10 minutes of work with the DeWalt and Black and Decker 5 amp battery, suggesting that serious users should use the 6 amp battery in this angle grinder.

Makita has always been a familiar name for any craftsman. The Makita XAG20Z 18V Angle Grinder is another professional-grade Makita tool that has received strong praise from owners for its excellent power. That power comes at the cost of battery life. Owners generally recommend the Makita 18-volt LXT Lithium-Ion battery, the largest in the range, as standard drill batteries don't last very long.

The Makita XAG20Z 18V is another angle grinder featuring brushless motor technology that is fast becoming the industry standard for battery-operated power tools. This grinder features Makita's soft-start design, which means it won't suddenly jerk sideways when you start it up. This feature alone can make the difference between choosing this grinder versus something like it.

The Makita XAG20Z 18V angle grinder has other nice design options, such as a triple LED charge indicator light that lets you quickly know the battery level, and a quieter, more durable spiral bevel gear design. Another great option from Makita engineers is the shifter switch, which enhances your ability to put more quality into your work.

The Porter-Cable PCC761B 20V MAX Lithium Bare Cutter/Grinder is designed for tool-less adjustment and safety guard replacement, allowing you to quickly switch from cutting wheel to grinder. Spindle locks also provide the ability to change wheels by hand, potentially saving a spot on your tool belt where you no longer need to carry a wrench.

Running at 8500 RPM, this grinder has similar cutting power to the 9000 RPM, but the 500 RPM difference brings out the excellent battery life that owners report. The Porter-Cable PCC761B 20V MAX features a cast metal gear housing for heat dissipation. This grinder is longer and heavier than many cordless models and creates less vibration due to the weight.

The Porter-Cable PCC761B 20V MAX is designed with an overmolded chamfered handle, which means that the handle partially surrounds a central core to isolate vibrations from the hand. The sander's side handle can be mounted in any of three separate positions for maximum versatility when arriving at your job site. There is a trigger lock for easier grip for long grinds.

If you don't necessarily need a cordless grinder, or just want a quality backup grinder at an affordable price, the Craftsman CMEG100 Angle Grinder is worth a look. 6 amps of power and 12,000 RPM can handle some serious grinding. When your cordless batteries die or you just need some brute force, this grinder will handle business for you.

The Craftsman CMEG100 Angle Grinder features a tool-less safety guard that can be easily rotated or removed when changing wheels. It has a spindle lock that allows you to change the wheels manually too. This grinder has a three-position side handle so you can take advantage of the extra angle to get the job done better. Some owners have reported overheating issues, but with any power tool running at 12,000 RPM, you're going to have to watch the run time.

The Craftsman CMEG100 Angle Grinder features a contoured handle with an overmolded design. This type of grip will help minimize felt vibrations, which is always a welcome feature when it's time to get through a long day.

The DeWalt DWE43244N Angle Grinder is a professional-grade, heavy-duty grinder designed for serious professional applications. It's designed with paddle switches instead of slide switches for a better in-hand feel. This type of switch also offers more security as it locks until you flip a small safety lever to allow the switch to be pressed, when you release it it releases and automatically closes.

This grinder features a brushless motor for faster spins, cooler operation, and longer battery and motor life. The DeWalt DWE43244N Angle Grinder is designed with a recoil braking system that reduces inertia by coasting and slamming the brakes if there is binding, stalling or pinching under the wheel. There's also a feature called an e-clutch, which allows the wheels to coast under restrained loads to reduce the amount of inertia and torque movement.

The DeWalt DWE43244N angle grinder has a larger wheel diameter than the other machines in this roundup, at 5-6 inches instead of the 4.5 inches found on other grinders. DeWalt also designed a lanyard loop into the handle.
