Carmex Thread Mills Carbide - Hard Type - UN (UNC UNF UNEF UNS) - 1/4 x 20 - MT11

Carmex’s solid carbide thread mill in hard-type construction is built for industrial threading and chamfering in a single step. With an MT11 shank, it’s designed for die-and-mold shops and precision manufacturers that demand reliability when threading hardened materials and high-temperature alloys.

• Thread form compatibility: Supports UNC, UNF, UNEF, and UNS forms, enabling versatile threading with one tool.
• Nominal size: 1/4" major diameter with 20 threads per inch (1/4-20 UNC/UNF) for common fastener standards.
• Shank type: MT11 shank for rigid seating and high torque transfer in demanding machines.
• Material and coating: Solid carbide core paired with a high-wear, heat-resistant coating for extended tool life in tough materials.
• Multifunction capability: Executes both thread milling and chamfering in a single operation to cut overall cycle times.
• Rigidity and geometry: Increased cutting diameter enhances rigidity and minimizes deflection during deep or aggressive thread milling.
• Chip control: Ultra-fine grade delivers precise thread profiles with short, manageable chips for secure chip evacuation.
• Thread length: Thread length up to 2xD enables longer threaded features without tool changes.
• Ideal applications: Optimized for Die and Mold work, high-speed threading, and assemblies requiring durable, accurate threads.

This carbide thread mill is engineered to deliver accurate, repeatable threads across a spectrum of demanding materials—from hardened steels and cast iron to nickel-base alloys and titanium. By combining threading and chamfering in one tool, it reduces setup time, accelerates production, and improves surface finish and dimensional stability. The robust construction and specialized coating are purpose-built to withstand high cutting speeds, short chip formation, and the thermal demands of aggressive thread milling in the Die and Mold industry.
