Angle Grinder

Power, connectivity and a best-in-class user interface combine to make the Bosch GWS18V-45PSC 18V EC Brushless Connected 4-1/2 in. Angle Grinder a must-have product for tough grinding applications. The grinder features a Bosch EC brushless motor that offers maximum efficiency and low maintenance, plus connectivity that delivers next-generation control including mobile-

device-based maintenance review and performance notifications.


The Bosch GWS18V-45PSC grinder delivers outstanding performance, including metal cutting. This Bosch-exclusive design provides greater runtime and more power than similar cordless grinders with brushed motors. That means professionals can rely on a cordless grinder that delivers 9,000 no-load rpm, but doesn’t forego power in favor of maneuverability.


The grinder’s HMI interface provides a large screen that changes color based on grinder operating status: green for operational; yellow identifies an issue with the grinder like kickback; red means the grinder is offline; and blue means the grinder is connected to a mobile device. The corresponding free Bosch Toolbox app can be found at the Apple App Store® or the Google Play® Store.


The grinder’s interface works with the Bosch GCY30-4 Bluetooth® connectivity module, which provides next-generation user control from a mobile device. Users can customize the grinder, change the speed of the soft-start function, set the brightness of the LED, plus receive battery charge and safety information.


The grinder’s advanced electronics provide features including drop control, which shuts the tool off if dropped, and KickBack Control that shuts down the grinder’s motor should the tool become jammed. The grinder also has restart protection to prevent accidental start-up during battery insertion. Soft-start technology reduces start-up torque to ease into cuts.


The grinder features a 2-position vibration control side handle that provides greater control than previous generation Bosch cordless grinders. It also makes operation of the grinder less fatiguing for the user. The side handle can switch from left to right for additional control and a slim soft-grip design provides additional user comfort.
