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.

The Rotaries should be fully inserted into the chuck and tightened before using. Maximum speed to be used at is 20,000 RPM (Low - medium speed). Use below 10,000 RPM and they will not melt, crack or chip Perspex, Plexiglass or Lexon. Lubricate with WD40 or similar if using on aluminium to reduce loading 

They are available in both coarse and fine grit. You will be asked to select which grit you require when you add the product to your shopping cart.
