The Carmex DMTH Multifunction Thread Mill (Hard Type) is engineered for precise, reliable threading in demanding materials. Designed for professionals who work with ISO and UN thread profiles, it delivers consistent results across hardened steels, stainless alloys, and high-performance metals.

• Thread profiles supported: ISO and UN forms, including UNC, UNF, UNEF, and UNS, for versatile threading without swapping tools
• Cutting diameter: 5/16 in, optimized for strong, clean thread generation in a compact profile
• Shank size and compatibility: 1/2 in shank with MT11 compatibility for wide compatibility with standard toolholders
• Thread depth capability: Up to 2x the thread diameter, enabling deeper threads in a single setup when possible
• Flute configuration: 3–4 flutes designed to balance rigidity, chip evacuation, and threading stability
• Material and construction: Hard-type carbide substrate built to cut hardened materials and high-performance alloys with precision

This multifunction thread mill is ideal for production runs and prototype work where you need one tool that can handle a variety of thread forms and tough materials. Expect strong edge retention, dependable thread quality, and consistent results when threading components in automotive, aerospace, and mold-making applications. The combination of carbide durability, flexible thread-profile support, and a robust flute design helps you reduce tool changes, minimize downtime, and maintain tight tolerances across challenging materials and geometries.
