Features: X-Lock - tool less wheel lock system allows the installation / removal or X-Lock wheels in just a single action. Minimising down time and preventing over or under tightening of accessories.; eXtreme Protection Technology (XPT) - engineered for increased durability and longer tool life, XPT provides increased protection against dust and moisture for when the job takes you into harsh conditions. ; Active Feedback Sensing Technology (AFT) - sensors shut down the tool in the event of a kickback providing user protection. If the wheel rotation is suddenly forced to stop, such as the wheel jamming the motor automatically shuts down. ; Variable speed control - dial allows speed to be adjusted from 3,000 rpm to 8,500 rpm in order to correctly match the speed to the accessory and the application; Auto-Start Wireless System (AWS)* - compatible with AWS the angle grinder can be paired with a compatible vacuum for on demand dust extraction. AWS uses Bluetooth to wirelessly power on and off the extraction unit using the tools trigger. ; Constant Speed Control - maintains wheel speed under load to provide optimum performance in all applications. ; Soft Start / Anti Restart - wheel starts slowly then rapidly accelerates to maximum speed to reduce the initial start up shock. Anti restart restricts the tool from starting if the trigger is depressed when a battery is installed. ; Electric Brake - maximises productivity and user safety by rapidly slowing the wheel rotation after the switch has been released. ; Specifications: Voltage 40 V Max Wheel diameter 125 mm (5") Switch Type Slide Switch Electric Brake Yes AWS Compatible Yes No load speed 3,000 - 8,500 rpm Length 433 mm Weight 2.3 kg
