The Carmex Threading Tap is a precision spiral-flute tap designed for UNF threads, built for professionals who demand reliability in challenging materials and high-speed tapping. With its HSS-E composition, it delivers long tool life and consistent thread quality in manufacturing, repair, and fabrication settings.

• Size & thread: 5/8" diameter, 18 threads per inch (UNF)
• Flute design: Spiral flute for efficient chip evacuation and reduced clogging
• Material: HSS-E (high-speed steel with cobalt) for improved hardness and heat resistance
• Cutting geometry: UNF Supercut geometry for clean cuts and longer service life
• Application type: Suitable for UNF threading in demanding materials and high-speed tapping operations

By using this tap, you can achieve precise UNF threads with less risk of deformation or thread pull-out. The cobalt-enriched HSS maintains sharpness under heat, extending tool life in tough metals. Spiral-cut channels ensure chips clear quickly, reducing heat buildup and thread defects, which translates to better thread engagement and fewer rejects in assemblies. This tap supports faster setup and repeatable results for production runs, repair work, and high-precision assemblies in metalworking environments. For best outcomes, pair with appropriate lubrication and use proper tapping practices to maximize surface finish and tool longevity.
