• Made of HSS-G high-speed steel with TiAlN coating.
• Step Tip point for precise centring and progressive cutting.
• Spiral flutes for efficient chip evacuation.
• Greater resistance to wear and temperature.
• Visible diameter marking for quick identification.

The HSS-G step drill with TiAlN coating, spiral flutes and Step Tip point is a premium high-performance tool designed for maximum precision, cutting efficiency and durability in intensive work on sheet metal.

Made of HSS-G high-speed steel and coated with TiAlN (titanium aluminium nitride), it offers greater heat and wear resistance than uncoated versions. Its stepped conical geometry allows multiple diameters to be drilled with a single tool. The helical flutes improve chip evacuation and cutting smoothness, while the Step Tip point favours stable centring and controlled, progressive penetration. It is aimed at professional applications requiring high productivity and a long service life.
