Carmex Thread Mills Carbide – Hard Type are precision, solid carbide tools designed for demanding die and mold work and precision machining. Built to thread a wide range of materials, these mills combine threading and chamfering in a single pass to boost productivity without compromising accuracy. The MT11 shank and multi-diameter option set make them a versatile choice for high-speed, high-precision internal threads.

• Diameter range: 5/16", 9/16", 5/8", and 11/16" with 18 TPI (UNC/UNF/UNEF/UNS) to cover common coarse to fine thread specifications.
• Coating: High-wear, heat-resistant coating designed to extend tool life in challenging materials and high-temperature applications.
• Material: Solid carbide hard-type construction for exceptional rigidity and wear resistance in tough materials.
• MT11 shank: Compatible with standard tool holders for seamless integration into existing CNC setups.
• Multifunction design: Thread milling and chamfering performed by a single tool, reducing tool changes and cycle times.
• Increased cutting diameter: Improves rigidity and stability during heavy-duty threading and chamfering operations.
• Ultra-fine grade: Optimized for hardened materials, delivering precise, controlled cuts and short chip formation.
• Thread length: Up to 2xD, enabling deeper threads while maintaining strong wall integrity.
• Material compatibility: Excels on hardened steels and cast iron up to 62 HRc, high-temperature alloys, titanium, Hastelloy, Inconel, and nickel-base alloys.

This tool is purpose-built for the Die and Mold industry, delivering high cutting speeds, shorter machining times, and lower cutting forces thanks to its compact, rigid profile. By eliminating separate chamfering passes, it helps maintain tight tolerances, clean chip evacuation, and consistent thread quality across a range of tough materials.
