A powerful single-phase commutator motor ensures high performance of the tool, which is used for abrasive removal of corrosion from metal structures, cleaning and processing of welded seams, grinding and cutting of metal products in domestic conditions. Switching, as well as turning the product on/off, is conveniently carried out with one button without the need to transfer the tool from hand to hand. The position of the abrasive disc guard is adjusted by loosening and tightening the clamping screw. Three threaded sockets located on the gearbox housing allow the front handle to be installed in 3 positions. The gearbox housing has a spindle lock button for changing the interchangeable attachment (abrasive disc or other tool). The presence of service covers allows for quick replacement of carbon brushes.
