The Carmex Spiral Point UNC Supercut Threading Tap in HSS-E (No. 2 x 56) is a precision tool built for machinists who demand reliable UNC threading in demanding materials and high-speed operations.
- Material: HSS-E (high-speed steel with cobalt) for enhanced heat resistance and longer tool life.
- Design: Spiral Point geometry that efficiently channels chips away from the cutting edge, promoting cleaner starts and smoother cutting.
- Thread Type: UNC (Unified National Coarse) for versatile, standard-thread applications.
- Size & Length: No. 2 size with 56 mm overall length to balance rigidity and reach in medium-depth holes.
- Construction: Carmex Supercut design delivers durable performance under high-speed tapping and challenging material conditions.
With this tap, you gain consistent thread quality, improved resistance to wear in tough materials, and reliable performance in production environments. The combination of spiral point chip evacuation and cobalt-enhanced steel helps maintain smooth cutting action, reduces the risk of clogging, and supports efficient, repeatable results across jobs.
