Carmex Thread Mills Carbide - Hard Type is a precision threading tool designed for die-and-mold work and challenging materials. It combines thread milling and chamfering in a single operation to boost productivity while preserving tight tolerances on hardened bases and high-temperature alloys.

  • Material and coating: Solid carbide body with a high-wear, heat-resistant coating built to withstand aggressive cutting conditions and deliver extended tool life.
  • Thread forms supported: Optimized for UNC, UNF, UNEF, and UNS threads, with No. 5 and No. 6 diameters to cover common mold and precision threading needs.
  • Shank and geometry: MT11 shank for secure, vibration-free toolholding; geometry designed to enhance rigidity and stability during heavy cutting.
  • Multifunction design: Performs both thread milling and chamfering in one pass, reducing tool changes and overall machining time.
  • Chip control and finish: Ultra-fine grade tailored for hardened materials, producing short chips to improve process security and surface quality.
  • Thread length and reach: Capable of thread lengths up to 2xD, enabling deeper threads in die-and-m mold components without extra tooling.
  • Application focus: Specifically suited for the Die and Mold industry, delivering high cutting speeds, shorter machining times, and lower cutting forces with a compact profile.

Using Carmex thread mills means faster cycle times, fewer tool changes, and reliable, repeatable threads on hardened steels, titanium alloys, and nickel-base super alloys. The combination of a rigid cutting diameter, protective coating, and short-chip performance translates to consistent threading quality, reduced heat generation, and improved overall productivity in demanding manufacturing environments.
