Description
Carmex DMTH Multifunction Thread Mills are built for precision threading in demanding materials, combining ISO and UN thread profiles in a single, hard‑type tool. Designed for machinists who work with hardened steels, stainless alloys, and high‑performance materials, these mills deliver reliable, repeatable threads with confidence.
- Cutting diameter range: 1/4" to 3/8" (0.250"–0.375"), with 20 TPI thread pitch for versatile fastener applications.
- Thread profiles: Supports both ISO and UN thread forms (UNC, UNF, UNEF, UNS) for broad compatibility with different specifications.
- Depth capability: Threading depth up to 2× the thread diameter, enabling deeper, more robust threads in a single operation.
- Flute configuration: Multi‑flute design with 3–4 flutes to optimize chip evacuation, stability, and finish in tough materials.
- Shank type: MT11 shank for broad compatibility with common CNC toolholders and collets.
- Material and construction: Carbide substrate engineered for high wear resistance when cutting hardened materials, stainless steel, and high‑performance alloys.
This tool is ideal for precision threading in automotive components, aerospace fasteners, mold and die work, and precision engineering parts where strong, accurate threads are essential. The DMTH’s multifunction capability reduces setup time by handling multiple thread standards with one tool, while its deep threading capability and robust flute geometry support clean, consistent thread quality across batches. When comparing threading options, this Carmex thread mill offers a practical balance of range, durability, and versatility for rigorous machining environments.
