HSSE Cobalt Machine Tap DIN 376 Form B (Gun) UNC – Series 21490

The HEPYC 21490 series features HSSE cobalt machine taps with Form B (Gun) geometry and a thin shank, designed for fast and accurate threading of UNC threads in through holes up to 3×D. The gun point geometry pushes chips forward, ensuring excellent chip evacuation and consistent thread quality in CNC machining applications.

Manufactured to DIN 376 standards with ANSI/ASME B1.1 thread specifications and 2B thread tolerance, these taps provide reliable performance, excellent durability, and long tool life, while the thin shank design offers improved accessibility in restricted machining areas.
