Precise HSS-PM tap for demanding blind hole machining

This HSS-PM tap provides a well-conceived solution for the reliable cutting of metric fine threads in blind holes. The powder-metallurgical high-speed steel (HSS-PM) grants the tool an extremely fine and uniform micro-structure. This creates excellent conditions for stable cutting edges, long-lasting dimensional accuracy on the 60° flank angle, and a consistent threading process across various materials from structural steel to stainless steel.

Applications

This fine thread tap meets the high demands of professional mechanical engineering, toolmaking, and mold construction. It offers flexible application possibilities in both single-part and series manufacturing, wherever internal threads need to be reliably cut into blind holes. Its application range covers a broad spectrum of demanding materials, including structural, tooling, and tempered steel, as well as 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 extreme hardness and toughness. The optimized flute geometry of the tool ensures controlled chip evacuation out of the blind hole, directed against the cutting direction. Additionally, the resistant TiAlN coating provides high thermal stability and reduces abrasive wear during continuous industrial use.
