These high quality, robust stepped stainless steel screw mandrels are mounted onto a 2.35mm (3/32") shank. As they are a more hard wearing screw mandrel we recommend using these with our diamond slitting discs, soft wheel polishing discs, Airflex polishing wheels, pumice polishing discs, EVE Diapol Diamond Polishers, Silicon polishing wheels and more.

Ensure you have approximately 15mm of mandrel protruding from your collet for good working performance. If you are using these in a hobby rotary tool please ensure you have a 2.3mm collet or an adjustable chuck (Dremel Multi Chuck if using a Dremel)
