Overview

The Bosch GWS 18V-10 is a compact cordless angle grinder built for professional cutting and grinding tasks. KickBack Control provides an electronic safety system that detects sudden stalls.

In-Depth Look

Cordless angle grinders have reached the point where they genuinely rival corded models for most cutting and grinding tasks on site. The Bosch GWS 18V-10 is among the more refined options in the cordless 18V class, combining a brushless motor with electronic safety systems that are absent from most budget cordless grinders.

KickBack Control

KickBack Control is Bosch’s electronic safety system that monitors the rotational dynamics of the disc in real time. When the disc stalls suddenly — typically when it binds in a cut — the system detects the rapid deceleration and cuts motor power in milliseconds. This is the moment at which most angle grinder injuries occur, as a stalled disc can cause the tool to kick back violently toward the operator. KickBack Control does not replace safe working technique, but it provides a meaningful safety margin that standard grinders lack.

Restart Protection

Restart protection is a separate electronic feature that prevents the grinder from spinning up if the battery is connected with the trigger held in. This prevents unexpected starts when changing batteries on site — a common cause of incidents with conventional grinders. The operator must release and repull the trigger after any power interruption before the tool will run.

Brushless Motor and Battery Platform

The brushless EC motor delivers higher efficiency than brushed motors, extending runtime per charge and producing less heat during sustained use. The GWS 18V-10 is compatible with Bosch 18V Professional (blue range) batteries including the higher-capacity CORE18V packs for demanding applications.

115mm Disc Format

The 115mm disc is well-suited to pipe cutting, metalwork preparation, tile cutting, and grinding in tight spaces. For higher-volume grinding or cutting of larger sections, the GWS 18V-15 (125mm) or mains grinders are more appropriate.

Verdict

A well-built cordless grinder with KickBack Control and restart protection — meaningful safety features for any professional using the tool regularly in trade conditions.
