Learn more about Klarna
Description
The Carmex Threading Tap is a Spiral Point UNF Supercut tap built for precision threading in tough metals. It’s designed for professionals who need reliable, repeatable UNF threads and efficient chip control to keep production moving.
- Size & Thread: 9/16" diameter, 18 TPI UNF (9/16-18 UNF).
- Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance.
- Design: Spiral Point to aggressively push chips forward and maintain smooth cutting action.
- Chip Evacuation: Efficient spiral geometry reduces clogging and supports steady threading progress.
- Durability: Built to withstand high-speed threading and demanding materials with lasting performance.
When you use the Carmex UNF Supercut Tap, you’ll achieve clean, accurate threads with fewer reworks. The cobalt-enhanced HSS-E resists wear under heat, enabling faster tapping without sacrificing precision. The spiral point and proactive chip evacuation keep the process steady in through-hole applications, delivering reliable results across production runs and finishing parts to spec.
