Description

The Carmex Spiral Point UNF Supercut Tap in No. 8 x 36 is a precision threading tool built for machinists who demand reliable UNF threads in tough materials. Crafted from cobalt-enriched HSS-E, it delivers consistent cuts, heat resistance, and lasting performance in demanding threading operations.

  • Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance during extended use.
  • Threading type: UNF (Unified National Fine) compatibility for fine-pitch thread requirements.
  • Cutting design: Spiral Point construction that channels chips forward, reducing clogging and promoting smooth threading progress.
  • Size and length: No. 8 x 36, providing a standard UNF thread profile with a practical working length.
  • Performance: Optimized for high-speed threading and tough materials, delivering durable, repeatable results.
  • Durability: Cobalt content in the alloy enhances wear resistance for longer tool life in demanding environments.

With its spiral point geometry and cobalt-rich HSS-E, this tap delivers precise UNF threads with reliable chip control and sustained cutting performance. It’s well-suited for production runs, maintenance tasks, and fabrication projects where consistent thread quality and efficient operation matter most, helping you reduce rework and install fasteners with confidence.
