There are a many, many US companies that manufacture endmills that are either variable pitch or variable helix, but only a few that manufacture variable helix AND variable pitch endmills. That’s because varying both the helix and the pitch is a patent protected design. Hanita, SGS, Dataflute, and our manufacturer, Carbide Grinding Company (aka GorillaMill), are some of the few that do vary both. Except for GorillaMill, the few 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. We are proud to offer the GorillaMill to our customers and to be associated with them. Click here to visit their site

Our “A” GorillaMill runs 50 to 150 percent faster through all materials, at a greater chip load, than our very good, sub-micrograin, also made in the USA, “B” mill.

In fact, we have to present two different speed/feed recommendations because the difference is so great:

         A Speeds/Feeds

         B Speeds/Feeds

We keep stock to backup your specific carbide and hss machine tooling needs, even specials.
