The OSG Metric Spiral Flute Threading Tap is a precision tool for machinists who need clean, accurate threads in blind holes. Built from HSS-E with cobalt and finished with a steam oxide coating, it delivers durable performance and reliable heat resistance for small-diameter tapping tasks.
- Size: M3 x 0.5 (metric threading for blind holes)
- Material: HSS-E (high-speed steel with cobalt) for superior hardness and wear resistance
- Coating: Steam oxide coating reduces friction and extends tool life
- Flute Design: Spiral flutes optimize chip evacuation in blind-hole applications
- Application: Ideal for threading blind holes in metal components with high precision
The combination of cobalt-enriched HSS and steam oxide coating delivers outstanding cutting performance under heat, enabling consistent, accurate threads across multiple uses. The spiral flute geometry minimizes chip buildup and chatter, reducing rework and improving surface finish on small-diameter threads. This tap is well-suited for precision assemblies, fixtures, and repair work where reliable blind-hole threads are critical.
