Applications

This NC spotting drill is primarily used for accurately positioned centering and spot drilling on milling and turning centers. It offers high flexibility when machining structural steel, case-hardened steel, stainless steel, cast iron, as well as aluminum and other non-ferrous materials. The stable geometry supports efficient processes in both single-part and series production.

Special features

The combination of solid carbide and a TiAlN coating equips the tool with high resistance to thermal and mechanical loads. Due to the cylindrical shank, the drill can be securely fixed in standard chucks, promoting high concentricity for exact hole positions. All tools are supplied in a convenient packaging unit of 1 piece.
