High-Performance Threading in Non-Ferrous Metals

The HSS-E Alu-Tap for blind holes is a practical solution for producing metric internal threads with a 60° flank angle. This tool is precisely adapted to the specific machining characteristics of wrought aluminum alloys, cast aluminum alloys, as well as copper and brass. With its sophisticated geometry, the tap ensures effective chip evacuation from the blind hole, creating excellent conditions for high-precision threading in industrial metalworking.
