High-performance HSS-PM tap for blind hole applications

This HSS-PM tap provides a well-conceived solution for the reliable production of metric fine threads in blind holes. Thanks to its powder-metallurgical high-speed steel (HSS-PM) construction, the cutting tool is characterized by a very uniform and fine-grained micro-structure. This creates excellent conditions for stable cutting edges, dimensional accuracy on the 60° flank angle, and continuous threading operations in demanding materials ranging from structural steel to stainless steel.

Applications

The fine thread tap is aligned with the requirements of professional mechanical engineering, toolmaking, and mold production. It opens up flexible application possibilities in both single-part and series manufacturing where internal threads must be cut into blind holes. Its application range covers a broad spectrum of workpiece materials, including tempered steel, cast iron, and non-ferrous metals like copper, brass, and aluminum alloys.

Special features

Thanks to the powder-metallurgical manufacturing process, the user benefits from a highly balanced combination of hardness and toughness. The adapted flute geometry promotes controlled chip evacuation out of the blind hole against the cutting direction. Additionally, the TiAlN coating ensures high thermal stability and minimizes abrasive wear during continuous industrial use.
