Bosch makes corded and cordless angle grinders. The GWS18V-8 is the cordless 18V model with a brushless motor and kickback stop. Bosch corded grinders have been industry standards for decades.
Bosch 18V Platform
The GWS18V-8N runs on Bosch CORE18V batteries. Bosch's 18V ecosystem is smaller than DeWalt or Milwaukee, but the grinder itself competes well on specs.

Frequently Asked Questions
What is Bosch KickBack Control?
An accelerometer in the tool detects sudden rotation (a kickback event) and cuts power to the motor within milliseconds. Similar to Milwaukee's RAPIDSTOP and Makita's AFT. All three are genuine safety features, not marketing fluff.
Is the Bosch corded grinder worth the premium?
The GWS13-50VSP has variable speed from 2,800 to 11,500 RPM. That low-end matters for surface finishing on stainless steel and aluminum where high RPM causes heat discoloration. If you only grind or cut carbon steel, a cheaper fixed-speed corded grinder is fine.
