The Carmex Spiral Point UNF Supercut Tap in HSS-E is a precision threading tool designed for flawless UNF threads in demanding materials. Built for machinists and shop environments that demand durability, consistency, and fast production, it delivers dependable performance job after job.
- Diameter & Thread: 7/16-20 UNF threads for fine-pitch, high-precision tapping in hard alloys.
- Material: High-Speed Steel with cobalt (HSS-E) for enhanced hardness, wear resistance, and heat tolerance during demanding tapping operations.
- Flute Design: Spiral Point (gun-point) geometry that drives chips ahead and promotes clean, uninterrupted threading in through-holes.
- Durability: Precision-ground flutes and cobalt content provide longevity under high-speed use and tough workpieces.
- Applications: Optimized for high-speed threading in challenging materials such as hardened steels and stainless alloys, reducing downtime and rework.
This tap helps you achieve consistent thread quality with fewer defects, thanks to reliable chip evacuation and steady cutting action. The spiral point design minimizes clogging and streaks, enabling smoother operation at higher speeds and delivering accurate UNF threads every time.
