Bosch Professional 06019N4100 Review

For the professional whose cordless toolkit is built around Bosch's 18-volt Professional batteries, adding a 125 mm angle grinder extends that platform into cutting and grinding — without the compromise of a DIY-grade tool. The GWS 18V-11 is designed as a workhorse cordless grinder: it takes standard 125 mm discs, includes KickBack Control and anti-restart protection, and is built to Bosch's Professional durability standards. It is the non-speed-preset version of the GWS 18V-11 S, offering the same core cutting and grinding capability at a slightly lower price point for users who do not need variable speed control.

The GWS 18V-11 is Bosch's Professional 18-volt cordless 125 mm angle grinder without the speed preselection feature found on the S model. It includes KickBack Control, anti-restart protection, and soft start. With 68 customer reviews averaging 4.6 out of 5 stars, user satisfaction is high. Sold as a bare tool without battery or charger.

This review examines the grinder's cutting and grinding performance on the Bosch 18V platform, the safety features, and how it compares to the S version for users deciding between the two.

The grinder drives standard 125 mm discs and is powered by Bosch 18V Professional batteries. The motor delivers adequate power for cutting steel, rebar, bolts, concrete, and tiles, and for light to medium grinding. KickBack Control detects sudden disc deceleration and cuts power to reduce kickback force. Anti-restart protection prevents accidental startup, and soft start eliminates the startup torque jerk.

The key difference from the GWS 18V-11 S is the absence of speed preselection — this model runs at a fixed speed rather than allowing the operator to dial in a specific RPM. For cutting and grinding, this is not a limitation; fixed speed is standard on most angle grinders. For applications like polishing or delicate surface preparation that benefit from lower speeds, the S model would be a better choice. The tool includes the protective guard, auxiliary handle, and spanner.

Customer feedback from 68 reviews averaging 4.6 out of 5 stars confirms the tool's power, safety features, and build quality. Users praise the KickBack Control and the convenience of cordless operation. The slightly lower price compared to the S model makes this a practical choice for users who need a cordless grinder for standard cutting and grinding and do not require variable speed control.

This cordless 125 mm angle grinder is designed for Bosch 18V Professional users who need a reliable cordless grinder for standard cutting and grinding applications and do not require the variable speed control of the S model.
