Why a polisher? 

        The RPMs for buffing/ polishing fall under 2500 for ideal use.  Many angle grinders are designed to run at 7000-11000 RPM which is too fast for the correct operating range of the resin pads. 

This Polisher can use 5" pads with the 005 kit. 

Polisher has 5/8-11 threaded spindle.  use with threaded velcro backpads and dry grinding resin polish pads.
