The Carmex Threading Tap is a purpose-built tool for professionals who need fast, reliable UNC threads in through-holes. Crafted from powder metal and designed with a spiral-point geometry, it thrives in demanding materials and high-speed tapping.

  • No. 2 x 56 UNC: Spiral-point tap engineered for Unified National Coarse threads in through-holes.
  • Material: Powder metal construction delivers durability and wear resistance for repeated use in tougher materials.
  • Geometry: Spiral Point (gun-style) design channels chips forward to minimize clogging and maintain smooth cutting action.
  • Drive Type: Square shank compatible with standard tap wrenches and tooling setups for secure, precise engagement.
  • Application: Optimized for UNC threading in a range of metals, including challenging substrates where clean, accurate threads matter.

This tap helps you achieve clean, consistent threads with less downtime due to chip buildup. The spiral-point design pushes chips ahead, reducing backward pressure and improving permitted feed rates in high-speed operations. Powder metal construction contributes to a longer tool life in demanding environments, while the square shank provides reliable engagement with common tapping equipment. Ideal for machine shops, fabrication work, and maintenance tasks that require robust UNC threading without compromising accuracy.
