The Carmex MT Thread Mills are built for anyone who needs precise, reliable internal threading in a cost‑effective package. Designed for CNC milling, this solid carbide tool handles UNC/UNF/UNEFS/UNS internal threads with a 3/8‑16 profile and MT7 shank, delivering consistent results across materials and runs.
- Threading capability: Internal thread milling designed for UNC, UNF, UNEF, and UNS standards, enabling accurate, finish-quality threads in holes.
- Cutting size: 3/8" cutting diameter with 16 threads per inch (3/8-16) for common fastener sizes.
- Flute configuration: Multi‑flute design (3–5 flutes) to improve rigidity, chip evacuation, and threading efficiency.
- Material and construction: Solid carbide for exceptional hardness, wear resistance, and long tool life in demanding materials.
- Shank compatibility: MT7 shank for secure clamping and broad compatibility with standard MT7 toolholders.
- Precision and efficiency: Optimized geometry reduces cycle times and delivers smooth, reproducible internal threads.
This MT thread mill is ideal for production environments and job shops aiming to streamline internal threading without resorting to tapping. The combination of carbide durability, a versatile multi‑flute design, and a robust MT7 shank translates to fewer tool changes, tighter tolerances, and cleaner thread surfaces—making it well suited for threaded holes in automotive components, hydraulic manifolds, pneumatic fittings, and precision assemblies.
