Is the Wapentake 21V grinder brushless?

Yes. It uses a brushless motor rated at 11,000 RPM, which generally means less wear and longer motor life than a brushed design.

How long does the battery take to charge?

The included 2A charger fills the 4.0Ah battery in about two hours.

What comes in the box?

The kit includes the grinder, a 4.0Ah battery, a 2A charger, a wrench, a grinding wheel, a cutting disc, a flap disc, a toolbox and a user manual.

Can it cut metal and remove rust?

Yes. It accepts cutting and grinding wheels and is intended for wood, metal and rust removal tasks.

Does it use standard 4.5-inch discs?

It works with cutting and grinding wheels, but confirm the disc size and arbor in the manual before buying accessories.

Is it a good choice over a corded grinder?

It trades the unlimited runtime of a corded grinder for portability. For heavy continuous work a corded model is stronger; for occasional jobs away from an outlet it is more convenient.

Our take on the Wapentake 21V Cordless Angle Grinder, 4.0Ah Battery Fast Charger

The Wapentake 21V is a cordless angle grinder built around a brushless motor that spins at 11,000 RPM. It ships with a 4.0Ah battery, a 2A charger that fills it in about two hours, and a kit of cutting, grinding and flap discs plus a wrench and toolbox. The brushless motor and included accessories put it ahead of many budget brushed grinders, but at 4.1 stars from 37 ratings it is not a proven workhorse. It suits light-to-medium cutting, grinding and rust removal on metal and wood around a home shop, not all-day industrial use.
