Bosch GWS 18 V-10 SC 125mm/5\" Angle Grinder, 2x 5.0Ah Batts & GAL 1880 CV Charger in L-Boxx 06019G347D The Bosch GWS 18 V-10 SC 125mm/5\" Angle Grinder has an intelligent fast brake system for the highest user protection that stops the disc after switching off in 2 seconds, and the electronic unit generates a polarity reversal inside the motor – thereby the rotor is retarded and disc stops. New keyless nut (consisting of an upper and a lower part) will further avoid spin-off; the lower part can rotate with accessory while the upper part is fixing the nut and disc on the spindle during braking process.
