Description

The Carmex Threading Tap is a precision forming tap (roll) designed for UNF threads, built for machinists and shops that demand consistent, burr-free results. Crafted from durable powder metal, it delivers reliable performance in tough materials and high-speed threading tasks. Carmex Forming Tap

  • Size x Pitch: 5/16" diameter x 24 UNF
  • Tap Type: Forming (Roll) tap for plastic deformation threading that forms threads rather than cuts them
  • Material: Powder metal construction for enhanced durability and wear resistance
  • Geometry: UNF Supercut geometry that promotes efficient chip formation and clean thread profiles
  • Applications: Ideal for UNF threading in challenging materials and high-speed production environments

With forming action, this tap creates strong, tight threads that improve fastener engagement and reduce scrap. The powder metal construction stands up to rigorous use, delivering longer tool life and consistent results across batches. The UNF Supercut design ensures precise thread form and reliable performance in demanding materials, making it a practical choice for precision threading projects and high-throughput operations.
