The carbon brushes have been significantly improved, reducing the need for servicing. The grinder also has Constant Electronic for maintaining a constant speed, even under heavy load, and a new clamping system for precise work. It has cut-out carbon brushes for motor protection, double sealed ball bearings for a long lifetime, and rubber-bedded ball bearings to reduce vibration sensitivity. The tool is suitable for stationary use and has a no-load speed of 28,000rpm. It also has various functions such as Champion motor, Direct cooling, Soft start, Overload protection, and KickBack Stop. The noise and vibration levels have been measured according to EN 60745 standards, with a total vibration value of 8.0m/s for surface grinding up to a diameter of 50mm and 3.0m/s for surface grinding up to a diameter of 25mm. The A-rated noise level is typically 89 dB(A) for sound pressure and 100 dB(A) for sound power,
