Description
Carmex DMTH Thread Mills are a multifunction threading solution crafted for precision in hard materials. Designed to cover both ISO and UN thread profiles, these tools excel in demanding applications and pair reliability with versatile performance.
- Thread profiles: Supports ISO and UN thread forms, including UNC, UNF, UNEF, and UNS, for flexible threading in a single tool.
- Material versatility: Engineered to cut hardened materials, stainless steels, and super/high‑performance alloys with consistent results.
- Depth capability: Thread depth up to 2× the thread diameter, enabling deeper threads per setup for strong, reliable joints.
- Flute configuration: Multi-flute design (3–4 flutes) improves chip evacuation and stabilizes cutting in tough materials.
- Size options: Available in No. 4, No. 5, and No. 6 with a 40 mm length, suitable for a range of hole sizes.
- Shank and compatibility: MT11 shank delivers strong compatibility with standard milling machines and setups.
The DMTH line focuses on delivering precision threading across a broad material spectrum, making it easier to complete fastener holes, threaded pockets, and joining features in modern manufacturing. With its ability to handle deep threads and mixed thread profiles, this tool helps reduce tool changes and increase productivity, while maintaining accurate pitch and clean thread finishes in demanding environments.
