The HSS TiAlN step drill bit has a drilling diameter ranging from 4 to 20 mm. It is designed for drilling into non-ferrous metals and plastic materials. Made from high-speed steel (HSS), it offers increased cutting ability and wear resistance.

The TiAlN (titanium-aluminum nitride) coating significantly enhances the wear resistance of the bits and allows for increased cutting speeds, making it ideal for processing difficult-to-cut materials and situations where the bits are subjected to high thermal loads due to a lack of coolant.
