The Carmex Threading Tap - Spiral Flute - UNC Supercut Tap - HSS-E in 7/8 x 9 is built for machinists who demand durable, precise UNC threading. Designed for tough materials and high-speed tapping, it delivers reliable, repeatable threads with minimal tool wear.

• Size & Thread: 7/8" diameter, 9 UNC threads per inch (7/8-9 UNC)
• Flute Design: Spiral flute for efficient chip evacuation and smoother cutting
• Material: HSS-E (high-speed steel with cobalt) for superior heat resistance and extended tool life
• Cutting Geometry: UNC Supercut geometry for clean thread profiles and consistent engagement
• Applications: Optimized for tough materials and high-speed tapping in production environments

This tap delivers precise UNC threads in demanding metals, with a design that helps keep chips moving away from the cutting edge. The cobalt-enhanced HSS ensures the tool stays sharp longer under heat, making it a reliable choice for repetitive tapping tasks in automotive, fabrication, and industrial machining settings. Its spiral flute minimizes plugging and chatter, contributing to smoother operation and better thread quality from start to finish.
