Superior tool life.

Helios fine-pitch carbide gear cutting tools are ground to maintain tooth profile accuracy from the front to nearly the back of the tooth, promoting longevity in re-sharpenings per tool. This is accomplished without altering flute widths, providing you a tool with up to 15% longer tool life compared to typical tools.

Superior coatings.

We offer Oerlikon Balzers Balinit® gear tool coatings, such as TiAlN (“Futura Nano”), AlCrN (“Alcrona”), and the latest generation, "Altensa," which offers up to 30% longer tool life in aggressive cutting conditions. Additionally, we offer AlTiCrN (“Exxtral Silver”), AlCrTiN (“Tigral”), and TiAlCN (“Variantic”) from Voestalpine Eifeler Coatings.
