Premium Cutting Tools

We offer the Helios full line of gear cutting tools including hobs, shaper cutters, and milling cutters in both bore and shank type designs. The Helios line of cutting tools also comes in several materials such as carbide, high speed steel, and state-of-the-art matallurgical materials that increase tool life while controlling cost.

All Helios gear gutting tools can be provided up to AGMA AAA specifications.

Superior Materials

Helios medium- and coarse-pitch cutting tools are produced using a state-of-the-art high speed steel material for green cutting applications. This metal can provide superior tool life versus typical high speed steels and can approach the performance of carbide tools. Even more impressive, this increase in tool life comes at a cost comparable to high speed steel!

Superior Tool Life

Helios fine-pitch carbide gear cutting tools feature a significantly superior tool life compared to typical tools. These tools are ground such that the tooth profile is 100% accurate from the front to the back of the tooth. This is accomplished without altering flute widths, providing you a tool with a significantly longer tool life. For comparison, typical hobs have an accurate tooth profile only about 23 from front to back.

Superior Coatings

We also offer fast delivery times and a variety of tool coatings, such as TiN, TiAlN (“Futura Nano”), AlCrN (“Alcrona”), AlTiCrN (“Exxtral Silver”), AlCrTiN (“Tigral”), and TiAlCN (“Variantic”). All coatings are provided by our local Balzers or Eifeler-Lafer facilities.
