The Carmex MTB solid carbide thread mills with through coolant are engineered for precise internal threading in holes, delivering reliable performance with UNC/UNF/UNEFS/UNS thread forms. Built on the MT line, this tool leverages through-bore cooling to keep cutting edges cooler and ensure smooth chip evacuation during deep threading operations.

• Through coolant bore: Coolant flows through the tool to the cutting edges, enhancing chip removal and cooling during threading.
• Solid carbide construction: Rugged, wear-resistant material that maintains accuracy and extends tool life under demanding use.
• Thread forms supported: Compatible with UN family threads including UNC, UNF, UNEF, and UNS for versatile internal threading tasks.
• Size and pitch: 7/8" diameter with 14 threads per inch (7/8 x 14) suited for common internal-threading applications.
• Shank type: MT7 Morse taper shank for broad compatibility with a wide range of milling machines.

Through-coolant threading reduces heat buildup and facilitates consistent chip clearance, enabling higher machining confidence and stable thread quality across production runs. The tool’s carbide rigidity supports tight tolerances and clean thread profiles, while the MT7 shank simplifies setup and integration into existing workflows. This combination is particularly beneficial for precision components in industries like aerospace and automotive, where reliable internal threads and efficient production matter most.
