Description

Carmex Thread Mills Carbide – Hard Type is a versatile, high-performance threading solution designed for precision work across a wide range of challenging materials. Built for Die and Mold shops and precision machining environments, this MT11 shank tool delivers reliable thread milling and chamfering in one streamlined operation.

  • Tool type: Solid carbide thread mills with a hard-type construction engineered for tough materials and demanding cycles.
  • Thread forms: Supports UN, UNC, UNF, UNEF, and UNS thread standards in sizes from 5/16" to 11/16" with 24 threads per inch.
  • Material & coating: Ultra-fine grade carbide with a high-wear, heat-resistant coating for longevity in hard steels, titanium alloys, and nickel-base alloys.
  • Rigidity & stability: Increased cutting diameter enhances rigidity and stability during heavy cuts and high-speed milling.
  • Multifunctionality: Handles both thread milling and chamfering, reducing setup time and improving overall productivity.
  • Chip control: Designed to produce short chips, strengthening process security and simplifying evacuation in tight cavities.
  • Thread length: Capable of thread engagement up to 2xD, enabling efficient deep threads without excessive tool wear.
  • Shank: MT11 shank provides secure, rigid tool mounting across a broad range of tool holders and CNC mills.
  • Ideal applications: Exceptional for hardened steels up to 62 HRc, cast iron, high-temperature alloys, titanium alloys, Hastelloy, Inconel, and nickel-base alloys—especially in Die and Mold manufacturing.

This carbide hard-type thread mill is engineered to deliver high cutting speeds, shorter machining times, and lower cutting forces through its compact profile. The combination of robust coating, ultra-fine grade hardness, and a design optimized for both threading and chamfering makes it a dependable, single-tool solution for precise, repeatable threads in challenging materials.
