Innovative, brushless motor technology - higher performance, more compact dimensions, longer battery life and longer battery life. Ultra flat gear head for working at sharp angles down to 40°. Epoxy resin armoured windings protect the motor against abrasive dust particles. Optimized fan system â effectively cools the angle grinder and electronics during use and increases the service life. Perform & Protect: Electronic brake stops the disc reliably in seconds (2 seconds). Perform & Protect: Electronic coupling switches the device off automatically when blocking and thus protects the user and the machine. The combination of electronic clutch and brake minimizes the risks of kickbacks even more effectively. Overload protection for protection of user and machine. Restart protection â accidental start-up of the angle grinder at battery change ruled out. Grillee for cooling air vents â protect the engine from coarse dust particles. Quick adjustment of protective hood without tools. As standard in T STAK® Box II as basic type (without batteries and charger) optimally suitable with already existing 18 Volt XR or 54 Volt XR FLEXVOLT batteries each of all Ah classes.This text is machine translated.
