Description

Engineered for precision Unified National Fine threading, the Carmex Spiral Point UNF Supercut Tap (5/8-18 UNF) delivers reliable performance in hard materials and high-speed production. Built for machinists and fabrication shops that require clean, accurate threads with minimal downtime, this tap combines strength, heat resistance, and efficient chip control.

  • Thread Size: 5/8-18 UNF
  • Design: Spiral Point (Gun Point) geometry to push chips forward and improve thread quality
  • Material: HSS-E (high-speed steel with cobalt) for enhanced heat resistance and extended tool life
  • Chip Management: Spiral flutes channel chips away from the cutting edge for efficient evacuation and reduced clogging
  • Durability: Cobalt-enriched composition increases hardness and wear resistance in tough materials
  • Applications: Ideal for high-speed tapping in hard metals requiring UNF threads
  • Brand & Series: Carmex UNF Supercut Tap

With this tap, you can achieve consistent UNF threads with reliable accuracy and a smooth finish, even in demanding materials. The spiral-point design directs chips out of the hole, reducing friction and downtime. The cobalt-enhanced HSS-E construction stands up to the heat of fast tapping, preserving edge life and extending tool life in production environments. This makes the Carmex UNF Supercut Tap a dependable choice for professional shops, repair tasks, and precision assemblies where thread integrity matters.
