Description
The Carmex MTB Thread Mills are high-precision solid carbide tools designed for UNJ threading with through-bore cooling, ideal for shops demanding tight tolerances and reliable chip evacuation.
- Through-Coolant Bore: Coolant is delivered through the bore to the cutting edges, enhancing chip removal and cooling in deep or tight threaded holes.
- Solid Carbide Construction: Rugged, wear‑resistant body that maintains dimensional accuracy under demanding threading operations.
- UNJ Thread Compatibility: Supports UNJ, UNJC, UNJF, and UNJS thread forms for versatile threading across common standards.
- Size and Interface: 3/8" cutting diameter with 24 threads per inch (3/8 x 24) and MT7 shank for broad machine compatibility.
By combining through-bore coolant with a robust carbide design, these MTB thread mills improve chip clearance, reduce re-cutting, and extend tool life. The result is more consistent thread quality, reduced downtime, and greater cost‑efficiency across precision threading projects in automotive, aerospace, and general manufacturing environments.
