## Overview

The GM12R4 Gorilla High Performance Carbide End Mill features a 4-flute design with a 1/2" diameter and 1-1/4" length of cut, coated with advanced GMX-35 nano-grain carbide for superior strength and durability. Patented variable flute geometry minimizes chatter and vibration, while GMP Edge Prep enhances tool life and finish quality. Made in the USA and fully resharpenable, this end mill excels in aggressive machining across a wide range of materials.

## Description

"WEAPONS OF MASS PRODUCTION" While you’re in the "" go with the "Gorilla". Gorilla Mills, Phenoms, The Sasquatch, Silverbacks, Knuckledraggers and Baboons are so high performance it’s stupid. Variable flute and index design which cancels out chatter, harmonics and vibration. This family of apes with piss poor attitudes is recommended for aggressive machining applications in all materials including, stainless, Inconel, titanium, tool steels, aluminums and hardened materials. The 4 and 5 flute Gorilla Mills are patented under 7,153,067 and 7,367,754. All are produced with the highest Transverse Rupture Strength (TRS) nano-grain carbide substrate available. All are GMP Edge Prepped to hone the cutting edge in a controlled environment to reduce the fracturing that occurs to the cutting edge during the milling process while greatly increasing tool life and enhancing finish. Completely resharpenable and can be run dry or wet.Gorilla Mill end mills and cutting tools and Gorilla Drills are manufactured and sharpened at our North American plant outside of Milwaukee, Wisconsin. Our modern facility has been producing and sharpening cutting tools for the aerospace, automotive, medical and manufacturing industries for well over 30 years. The marketplace is overwhelmed with variable helix end mills. Like the Gorilla Mill, some are patented, most are not. One thing that matters most is performance in the machine tools. Gorilla Mills will reduce chatter, decrease cycle times, extend tool life and create a superior tolerance and finish. Prepare for battle. Make sure there's a Gorilla Mill on board.
