··(Other less common, pressure angle gear tools are available to rent or purchase as needed.)

Materials: steels, hardened steels, pre-heattreat steels, stainless steels, cast iron, aluminums, delrin (aceytl), nylon, uhmw and other plastics, non-metallics (phenolics), brass and bronzes, graphite, titanium, monel, inconel. We can and have made internal gears out of many other materials as well.

Internal Helical Gears

Although we do not get much call for them, some of our machines that produce Internal gears will also manufacture Internal Helical Gears.

For easy to understand technical information about Internal Gears… click on the Technical Section tab from our home page. Send us your gear samples or machine parts (new or worn) for our complete reverse engineering service.

Depending upon the complexity of your samples, in many cases, there is no charge for reverse engineering.
