The Carmex DMTH Multifunction Thread Mills are engineered for precise internal threading in hard-to-cut materials. Designed for shops that need both ISO and UN thread profiles in a single tool family, these hard-type mills excel on hardened steels, stainless steels, and high-performance alloys.

• Thread profiles: Supports ISO and UN threading, delivering versatility for a wide range of applications.
• Metric sizes: Metric thread options including M16, M17, and M23 × 2 to fit common and specialized components.
• Shank: MT11 shank provides stable seating in standard tool holders for demanding cuts.
• Head geometry: Hard-type design optimized for cutting tough materials with consistent wear resistance.
• Flutes: Multi-flute configuration (3–4 flutes) enhances chip evacuation and cutting efficiency.
• Depth capability: Thread depths up to 2× the nominal diameter enable deeper threads in fewer passes.
• Material compatibility: Effective on hardened materials, stainless steels, and super/high-performance alloys due to robust construction and geometry.

These DMTH thread mills offer a comprehensive threading solution that combines profile flexibility, deep-thread capability, and durable performance. The result is reliable thread quality, reduced setup and tool-change times, and improved productivity for components such as housings, gear banks, connectors, and precision fasteners. Ideal for automotive, aerospace, moldmaking, and general precision machining environments where durable, accurate internal threads matter most.
