Carmex DMTH Thread Mills Multifunction (Hard Type, Metric, M4 x 0.7, MT11) are precision threading tools designed for demanding materials. Ideal for machinists and production shops, they deliver reliable ISO and UN thread profiles with strong performance in hardened steels, stainless alloys, and high‑performance metals.

• Thread profiles: Supports both ISO and UN thread forms for versatile internal threading needs.
• Thread depth: Capable of cutting threads up to 2x the thread diameter for deep or blind holes in a single setup.
• Flute configuration: Multi-flute geometry (3–4 flutes) enhances cutting efficiency and chip evacuation.
• Shank: MT11 shank provides rigid clamping and broad compatibility with standard toolholders.
• Size and pitch: Metric M4 x 0.7 threading for common fastener sizing in precision assemblies.
• Material reach: Engineered to perform in hardened materials, stainless steels, and high‑performance alloys with consistent results.

The DMTH line expands Carmex’s DMT thread mill family, delivering a durable, high‑precision solution for challenging threading tasks. Expect clean, accurate threads with steady pitch and reliable depth control, even in tough materials. The 2x depth capability reduces the number of passes and tool changes, boosting productivity in automotive, aerospace, tooling, and general manufacturing environments. The MT11 shank and 3–4 flute design work together to maintain stability, improve surface finish, and extend tool life across a range of thread sizes and profiles.
