Perma-Grit Rotary File – Wide Cone – Coarse
The Perma-Grit® Rotary Files have a 3mm arbor and are suitable for use with Minicraft, Dremel, Flexi-drives and similar small drills.
Unlike the cheap Rotary files that are now so readily available, these Perma-Grit® ones will not clog up and burn out, thus giving you years of trouble free use.
Perma-Grit® Tools do not lose their cutting edge like conventional tools and will outlast sandpaper thousands of times, giving you years of use.
They cut, sand and shape hard & soft woods, plastics, fibreglass, carbon fibre, tiles, bricks, ceramics, glass, white & blue foam, aluminium (lightly spray with WD40 to eliviate loading), etc. The tools don't clog easily with normal use, but those that do get clogged with glue, resin, paint, etc, can simpily be cleaned with any solvent.
