High-performance HSS-E tap for metric fine threads

When machining demanding blind holes, the HSS-E tap for metric fine threads proves to be a reliable tool in the metalworking industry. The 60-degree flank angle and specialized geometry ensure a clean formation of the fine thread, while the chips are safely evacuated from the blind hole. The cobalt-alloyed HSS-E material grants the tap high temperature and wear resistance, making it an excellent choice for professional use across various machining tasks.

Applications

This tap is a well-thought-out solution for industrial metalworking, mechanical engineering, and maintenance operations. The design is optimally tailored for the production of blind hole threads, where chip evacuation must occur upwards. The broad suitability for structural and tempered steels, stainless steel, cast iron, and non-ferrous metals such as aluminum and copper makes this cutting tool a versatile option for diverse manufacturing processes.

Special features

The cutting tool convinces with its manufacturing from premium HSS-E, which offers improved hot hardness compared to conventional high-speed steel. This supports efficient workflows even when processing tough materials. The precisely engineered cutting geometry opens up flexible application possibilities on conventional machines as well as on CNC-controlled machining centers.
