Professional machining of Imperial pipe threads

With the high-performance HSS-E tap for blind holes, you can produce accurately fitting Imperial pipe threads with a flank angle of 55°. The high-quality high-speed steel (HSS-E) provides an excellent basis for smooth cutting processes and reliable tool life. Thanks to its special geometry for blind holes, chips are safely evacuated, supporting clean and precise thread creation.
