Product Spotlight

  • Heavy Roughing in High TEMP Alloy | GMS² Coatings

    Based off the original Patented 4-flute Gorilla Mill, the Gorilla Mill Yeti is built tough for heavy roughing in all materials especially high temperature alloys. Its GMS2 coating and geometric enhancements allow for work on difficult-to-machine materials including: Inconel, Waspaloy, Hastelloy, Rene, Stellite, 17-4 SS, 15-5 SS, 13-8 SS, and Titanium. The Gorilla Mill Yeti is a monster in full slotting applications with very large material removal rates in all materials.

  • GMS²

    Introducing a revolutionary, newly formulated, PVD coating process. GMS² marks a breakthrough in PVD deposition technology. The performance and hardness stem from the coating’s unique structure. GMS² is specifically designed to punish high temp alloys and is stock standard on the new Gorilla Mill Phenoms.

GMP EDGE PREP

The tool edge preparation process adds strength to the tool cutting edge, lengthens usable tool life, minimizes the propensity of the edge to chip, improves part quality and consistency, and enhances work piece surface finish.

With GMP Edge Prep, we have taken edge preparation to the next level, making it a science. Now the technology and equipment exists to overcome nearly all the current processing problems and to produce a tool that will yield optimum performance in any given operation or application.

  • Quality Assureance

    Our primary responsibility is to ensure the accuracy and consistency of product being manufactured. We have an array of quality inspection equipment including three Eurotech PG1000’s with up to 145x magnification, a Leica M205 C computerized photo microscope with up to 500x magnification, a Zoller pomSkpGo for edge prep measurements at 100x magnification and two Zoller Genius3 machines which are CNC controlled programmable inspection machines with 50X magnification.

  • Regrinds

    The vast majority of your tooling that Gorilla Mill or anyone else manufactures can be re-sharpened and recoated to “like new” condition on one of our state-of-the-art CNC tool and cutter grinders at a fraction of a new tool’s cost. At Gorilla Mill, our goal is to show cost savings while maintaining a high accuracy rate. Whether it’s Gorilla Mills,® or other variable end mills, standard end mills, Gorilla Drills or any other high performance drills, Gorilla Mill has over 40 years of knowledge and experience to help your bottom line.
