Oscillating circuit 5 mm for maximum material removal rate with good surface quality. Non-slip rocker switch with dead man's function for safe starting and optional speed control. Vario-Tacho-Constamatic (VTC) full-wave electronics for grinding at material-appropriate speeds that remain constant under load. Electronic pre-setting of the desired speed range. Soft start minimizes surface defects when making contact. Unique brushless motor for maximum efficiency during grinding, even in continuous operation. Low vibrations for comfortable working in continuous use. Overload protection safeguards the motor against overheating. Separate main switch prevents accidental starting. Motor and disc brake enable quick shutdown of the machine. Dust extraction connection via the attachment of a versatile vacuum cleaner. Grinding plate with multiple perforations for effective dust extraction and longer lifespan of the abrasive. Easy to maintain thanks to the replaceable cable.
