About Micro-Mills™ & Bore-Mills™

Carbide Bore Mills™ have a special fine double cut and are used in place of mounted grinding wheels in jig grinding, with finishes in the 10 to 12 micro-inch range on cast iron, steel, nonferrous and many nonmetallic materials. Micro-Mills™ have a fine cut with chip breakers for light stock removal and finishes in the 6 to 8 micro-inch range; they work best on ferrous, non-work hardening materials and should not be oscillated (cut on the in-feed, burnish on the out-feed). Both outlast grinding wheels, and all are TiN coated at no extra charge.

  • All Bore Mills™ are TiN coated at no extra charge.
  • All Micro-Mills™ are TiN coated at no extra charge.
  • Bore Mills™ run at the same speeds and feeds as grinding wheels.
