Everything you need to strip the clear coat off of a Durabrite wheel. Then re-polish the wheel back out. Some optional selections include a full steel extender for a grinder: Steel 2″ Double Threaded Grinder Extension, and a rake: Buffing Wheel Rake. Full steel extender is needed for use on most models of grinders. Some Makita brand grinders need no extension. Feel free to add them onto the kit and save.
