Many of these versatile tools have been made over a period of years and we are confident buyers of sets of parts will be very satisfied. The grinder is offered in two styles:

The Quorn Mark 1

• Designed to accommodate foot-mounted motors.

• Designed for flange or face mounted motors. We offer castings and drawings for both styles of unit.
