Gorilla 4 Flute Square End GMS2 & WFT Coated End Mills, Inch, Super Bitchin' Performance, Made in USA

Gorilla Mill YETI End Mill Serials. Made in USA. 

4 Flute (INCH), Super Bitchin' Performance - Ferrous

• 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 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.
• Should be run at specific parameters. See “Speeds and Feeds” chart HERE.

Available in GMS2 and WTF Coating

Gorilla coatings are just a few thousandths of a millimeter thick but harder than steel; these low-friction coatings are extremely wear-resistant and chemically inert. The optimum coating is determined on the basis of both conditions of use and economic considerations.

• GMS2 Coating: Revolutionary 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.
