Finishers
Hardened Materials
Stainless, Inconel, Waspaloy, Hastelloy, Rene, Stellite, 17-4 SS, 15-5 SS, 13-8 SS, Titanium
The "Gorilla Mill" aggressive machining in all hardened materials.
• patented (7153067 7367754) variable flute and variable index design
• "GMP" edge preparation hones away the microscopic ridges in the flute edges——like a barber's strop
• "GMX-35" coated heat resistant to 1650ºF
The "Phenom"— 5 flute Gorilla endmill on steroids
• Radius corners for stonger edges and part radius.
• GMS² nano-composite coating: heat resistant up to 2200ºF
Finishers
Non-
ferrous
Material
Engineered to repel aluminum, copper, brass, plastic, and other non-ferrous materials
• High velocity, high material removal rate. Center cutting.
• Produced with the patented variable flute & index design, "GMP" edge prep, and highest TRS nanograin substrate
• ZRN coating is available, but is not necessary for aluminum with less than 5% silicon content
Hence the monicker:"Silverback"

New Carbide Endmills
We carry one brand of round tools and one brand of inserts (web pages in process).
Our variable helix, variable pitch, "GorillaMills" are made from the highest transverse rupture strength, nano-grain tungsten carbide substrate available.
These mills are engineered to run at 50 to 150 percent faster through all materials, at a greater chip load, than our very good, Standard sub-micrograin—also made in the USA—mill.
In fact, we present different speed/feed recommendations because of this difference
Several companies manufacture end mills that vary helix and pitch to reduce harmonic vibration. The varying helix and pitch is a patent protected design.
Most of them use a very good design patented by a Japanese company.
Gorilla, however, holds its own US patents. We have found that its improved designs usually produce 5 to 10 percent better performance than the other variable helix/pitch endmils, especially in harder materials like Inconel and titanium.
