DeWalt Cordless Grinders: Professional Power for Every Application
DeWalt cordless grinders have redefined jobsite mobility by delivering the torque and durability of corded equipment without the restriction of a power cable. From the versatile 20V MAX* platform to the high-performance 60V FLEXVOLT® lineup, DeWalt provides specialized grinding solutions for metalworking, masonry, and demolition. At Ohio Power Tool, we stock a massive inventory of DeWalt angle grinders, die grinders, and tuckpointers to help you tackle everything from light rust removal to heavy-duty concrete cutting.
20V MAX* and FLEXVOLT ADVANTAGE™ Technology
The 20V MAX* line is the go-to choice for trade professionals needing a compact, ergonomic tool for all-day use. For users who need an extra boost without moving to a larger platform, DeWalt’s FLEXVOLT ADVANTAGE™ grinders can identify when a FLEXVOLT battery is attached, unlocking up to 54% more power to power through demanding cuts in rebar and structural steel.
- Brushless Efficiency: DeWalt brushless motors run cooler and last longer, providing more work per charge for high-volume grinding.
- Perform & Protect™: Many models feature the E-Clutch® system, which shuts the motor down in less than a tenth of a second if a pinch or stall is detected.
- Kickback Brake™: An electronic brake engages with maximum force to stop the wheel quickly when a bind-up occurs, significantly reducing the risk of injury.
60V FLEXVOLT®: Industrial-Grade Cordless Performance
When the job requires maximum muscle, 60V FLEXVOLT® grinders deliver corded-equivalent power for heavy-duty fabrication and industrial maintenance. These tools are engineered to handle 4-1/2" to 7" wheels, making them ideal for thick metal plate cutting, weld dressing, and large-scale surface preparation. By operating at a higher voltage, these tools draw less current, maintaining high RPMs under load without overheating the motor or battery.

Frequently Asked Questions: DeWalt Cordless Grinders
Can I use a 20V MAX* battery on a 60V FLEXVOLT® grinder?
No. 60V FLEXVOLT® tools require a 60V FLEXVOLT® battery to operate. However, 60V FLEXVOLT® batteries are backward compatible and can be used to power your 20V MAX* tools, often providing significantly longer runtime.
What is the difference between a Paddle Switch and a Slide Switch?
A Paddle Switch (or "dead-man" switch) requires the user to hold it down to run the tool; if released, the tool stops. A Slide Switch can be locked in the "on" position, which is often preferred for long periods of surface grinding to reduce hand fatigue.
What does the "Perform & Protect™" label mean on DeWalt grinders?
This is DeWalt's safety standard. On grinders, it typically includes an E-Clutch® that shuts down the motor in under a tenth of a second during a stall, and a Kickback Brake™ that stops the wheel quickly when the tool senses a bind-up.
What is FLEXVOLT ADVANTAGE™ vs. standard 20V?
FLEXVOLT ADVANTAGE™ tools are 20V tools that feature upgraded electronics. When you plug in a 60V FLEXVOLT battery, the tool recognizes the extra power potential and increases its wattage output, providing up to 54% more power than when using a standard 20V battery.
Why does my grinder keep shutting off during heavy use?
This is likely the Overload Protection or E-Clutch® activating. DeWalt grinders sense when the motor is under too much stress or if the wheel has pinched. This prevents the motor from burning out and protects the user from kickback. Try reducing the pressure and letting the tool do the work.
Can I use 6" or 7" wheels on a 4-1/2" DeWalt grinder?
No. You should never use a wheel larger than what the tool and its guard are rated for. Doing so can cause the wheel to explode due to improper RPM ratings and leaves the user unprotected. Always use the correct guard size for the wheel you are using.
What is "Power-Loss Reset" or "No-Volt Release"?
The Power-Loss Reset feature prevents the tool from restarting automatically if power is interrupted (like a battery swap) while the switch is still in the "on" position. The user must cycle the switch off and on again to restart.
Are DeWalt cordless grinders good for cutting concrete?
Yes, especially when paired with a diamond blade and a dust extraction shroud. For heavy concrete work, the 60V FLEXVOLT® models are highly recommended due to their higher torque and ability to maintain RPMs through dense aggregate.
How do I know when to replace my grinding wheel?
You should replace a bonded abrasive wheel when it has worn down close to the hub or if you notice any cracks, chips, or water damage. For diamond blades, replace them when the diamond segments are flush with the steel core.
Where can I get DeWalt grinders serviced or repaired in Columbus?
As an authorized DeWalt dealer, Ohio Power Tool can help you with warranty information and sourcing genuine replacement parts like carbon brushes (for corded models), guards, and flanges to keep your tools running at peak performance.
