Our modern facility has been producing and sharpening cutting tools for the aerospace, automotive, medical and manufacturing industries for well over 40 years for use in the following applications:

  • High speed machining
  • Aluminum and nonferrous machining
  • Machining cast iron
  • Machining stainless steel
  • Machining inconel
  • Milling steel and etc.

Each Gorilla Mill® is designed on our 3D CAD simulator, then crafted on state of the art CNC, auto loading cutter grinders, assuring absolute perfection and repeatability.

Gorilla Mill® regrinds are sharpened using a modified version of the same program that is used to manufacture it new, thereby insuring 80% to 100% of a new Gorilla Mill's® performance. Our distributor network has grown enormously over the past years due to the popularity of this design. In most cases, Gorilla Mills® can ship the same day. Gorilla Mills® are routinely produced in special diameters, radii and lengths. Need a custom Gorilla Mill®? Let our staff of engineers work with you to design and manufacture your high performance end mill and cutting tool.


  • Kong 6 Flute End Mill
    Super Bitchin' Performance...

  • Variable flute and index design which reduces chatter and vibration. Radius corners for stronger edges and part radius. Recommended for aggressive machining applications in all materials. Should be run at specific parameters. Produced with the highest Transverse Rupture Strength (TRS) nano-grain carbide substrate available.
    Available in special diameters, lengths and completely resharpenable.
  • Lemur 2, 3, 4, and 5 Flute Chamfer Mills
    Standard and High Performance...

  • 2 and 4 Flutes are designed for improved finish and increased tool life, the Lemur general purpose chamfer cutters are a cost effective choice for countersinking and chimpfering. Un-coated or GMX-35 coated, the Lemur general purpose chamfer line provides high quality results in standard chimpfering operations.
    3 and 5 Flutes are designed for eye-popping high performance chimpfering and countersinking in all materials. The Lemur high performance chamfer line is designed in 3 flute (Zrn coated) and 5 flute (GMS² coated) configurations and “drop the mic” while achieving maximum finish quality in materials up to 55 Rc. 
    Available in special diameters, lengths and completely resharpenable.
  • Arsenal Picatinny Form, Rail & Attachment Cutters
    Super Bitchin' Performance...

  • Picatinny Rail  or “Pic Rail” cutters, Pic Rail Groove cutters and Attachment/Accessory cutters designed to MIL-STD-1913 specs with extra “Secret Squirrel Sh*t” performance enhancements. Gorilla Mill patented geometries makes milling the entire Pic Rail in a single pass easy peasy. Solid carbide high performance 3, 4, and 5 flute cutters manufactured right here in ‘Merica by "We The People". GMS² coated for high heat resistance, longer tool life and faster running speeds. Run all of the Gorilla Arsenal cutters with cocky-ass confidence in ferrous and non-ferrous materials. Run them in 6061, 7051, 300, 400 and PH series stainless, titanium, high temp alloys, high carbon steel, low carbon steel, somewhere in between carbon steel, rice pudding, concrete, a bowl of Lucky Charms® or lava! We don’t give two sh*ts what you run them in. JUST RUN THEM HARD!
