Distar Click-Lock 50 is a small magnetic backing pad for polishing porcelain stoneware and similar hard surfaces. It has a 48 mm rubber-faced pad and takes 50 mm polishing pads on steel holders that snap on magnetically, so you change grit in one click. Supplied with one backing pad and three steel holders.
It is made for engravers and rotary tools, not angle grinders, with a maximum speed of 6,500 rpm. Distar lists the Proxxon WP, LWB and LHW as compatible; it does not suit Dremel tools.
