The Mini Grind-O-Flex is designed for polishing and grinding intricate surfaces. Built-in flange construction insures perfect balance at speeds of up to 30000 RPM. The mini-wheel reduces labor costs on many applications which are currently finished with brushes, rubber points, felt bobs, or cartridge rolls. The quick-change feature allows you to quickly spin the wheel on and off with no special tools. High Performance Mini Wheels feature a completely new, more durable coated abrasive, designed from the ground up for demanding flap wheel applications.
