The Carmex Spiral Point UNC Supercut Tap (3/8 x 16) is a precision threading tool designed for professionals who demand reliable UNC threads in tough materials. Built for durability and speed, it delivers consistent results in demanding machining and tapping applications.

  • Size & Thread Type: 3/8" diameter, 16 threads per inch, UNC (3/8-16 UNC)
  • Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance
  • Geometry: Spiral Point for efficient chip evacuation and forward threading
  • Designation: UNC Supercut geometry optimized for clean, accurate thread formation
  • Application: Ideal for Unified National Coarse thread tapping in challenging materials
  • Performance: Designed for high-speed threading with reduced chip buildup and minimal clogging

This tap combines the durability of cobalt-enhanced HSS with a spiral-point design to push chips out of the thread path, reducing rework and downtime. Its robust construction and precise geometry help you achieve smooth, accurate UNC threads on tougher materials, making it a dependable choice for automotive, fabrication, and maintenance tasks where reliable taps matter.
