Our take on the DEWALT 20V MAX* XR Brushless Cordless 4-1/2 in.-5 in. Grinder (Tool Only)

This is DEWALT's brushless 20V MAX XR angle grinder, a cordless tool-only unit that takes 4-1/2 in. to 5 in. wheels and runs at 9,000 RPM with variable speed and a paddle switch. It stands out for the ANTI-ROTATION System, which shuts the tool down if it kicks excessively, plus Wireless Tool Control pairing with compatible DEWALT dust extractors. The best new price is $158.92 at Amazon as of November 6, 2026, with three stores listing it new. No battery or charger is included, so budget for those if you are not already on the 20V MAX platform.

Questions and answers

Is this grinder worth it over the older brushed DEWALT?
The brushless motor delivers more power and longer motor life, and it adds variable speed and the ANTI-ROTATION System. If you already own 20V MAX batteries, it is the better long-term buy.
What battery does it need?
Any DEWALT 20V MAX battery works. For sustained cutting, a 5.0Ah or larger XR pack gives noticeably longer runtime than a compact 2.0Ah.
Does it come with a battery and charger?
No. It is tool only, and the listing includes the grinder and a 5 in. Type 27 guard. Battery, charger and Tool Connect chip are sold separately.
Can it use 4-1/2 in. wheels?
Yes. It accepts both 4-1/2 in. and 5 in. wheels, and the included guard is sized for 5 in.
How does Wireless Tool Control work?
Paired with a compatible DEWALT dust extractor, the grinder can switch the extractor on and off as you start and stop the tool.
When is it cheapest?
Cordless bare tools tend to dip during DEWALT promotions and holiday sales. The current best is $158.92 at Amazon as of November 6, 2026, so compare against that during sales events.
