The Carmex Spiral Flute UNF Supercut Tap, crafted in HSS-E, is a precision threading tool built for Unified National Fine (UNF) applications. Designed for machinists, toolmakers, and metal fabricators who demand reliable, clean threads in challenging materials, it delivers consistent results from start to finish.

• Thread Type: UNF (Unified National Fine) threading for tight, accurate internal threads in a variety of metals.
• Size: 1/12 x 20 (1/12" nominal diameter with a 20 TPI UNF pitch).
• Flute Design: Spiral flute facilitates efficient chip evacuation, reducing clogging and maintaining smooth cutting action.
• Material: HSS-E (high-speed steel with cobalt content) for enhanced hardness, temperature resistance, and tool life.
• Cutting Action: Supercut geometry delivers crisp teeth and steady cutting through tougher materials with improved finish.
• Durability: Optimized for high-speed threading and demanding materials, helping extend tap life and reduce rework.
• Applications: Ideal for internal UNF threads in steel, stainless steel, and other alloys where precision and reliability matter.

With this tap, you’ll achieve precise UNF threads with fewer passes and less risk of tap binding. The spiral flute design aggressively clears chips, supporting higher speeds and cleaner cuts, while the cobalt-infused HSS-E construction resists heat and wear. This combination translates to accurate thread profiles, smoother tapping experiences, and reduced downtime in both prototype work and production tasks. Perfect for maintenance, repair jobs, or new builds that require dependable UNF threading performance.
