The six models with disc diameters ranging up to 150 mm come equipped with an advanced autobalancer system (see arrow). Recent test results have consistently shown that these models have lower vibration levels than the competition. Most importantly, they are always below the exposure limit of 5m/s2 set forth by EN 60745, explains the power tool specialist. This allows the machines to be used essentially all day long under normal working conditions. Real vibration control: The new Metabo autobalancer is integrated onto the drive shaft of the angle grinder, where it replaces the support flange. Oil-lubricated ball bearings move freely about inside the autobalancer. This provides maximum protection by offsetting the imbalances caused by cutting and grinding discs, says the manufacturer. Identified by the quality seal pictured below, Metabos technology does more than just improve the health of workers. It not only extends the service life of grinding discs, but also allows workers and machines to operate for longer periods at a stretch. More information...
