Learn more about Klarna
The Carmex MTB solid carbide thread mill with through coolant is engineered for precise internal threading in UN-series threads (UNC, UNF, UNEF, UNS). Built for shops that demand durability and reliable chip control, it combines rugged carbide with an innovative coolant-through design.
- Through-Coolant Bore: Coolant is delivered directly through the tool bore to flood the cutting zone, aiding chip removal and keeping temperatures in check for cleaner, deeper threads.
- Solid Carbide Construction: Premium carbide provides exceptional hardness and wear resistance, helping the tool withstand demanding threading operations and extend tool life.
- UN Thread Compatibility: Specifically engineered to mill UNC, UNF, UNEF, and UNS thread forms to standard profiles with minimal chatter and precise dimension control.
- 7/8 in Cutting Diameter x 9 in Length: Optimized size for a wide range of internal threading tasks, paired with an MT7 shank for secure, reliable performance on compatible machines.
- MTB Line Innovation: Advances the proven MT platform by integrating bore-through cooling, delivering enhanced performance and longer tool life in tough materials.
With through-coolant, chips are efficiently evacuated from the hole, heat is controlled at the cutting edge, and tool wear is reduced. This translates to more consistent thread quality, fewer tool changes, and improved productivity in precision machining—whether you’re working on automotive components, aerospace parts, or mold cavities that require robust UNC/UNF/UNEF/UNS threads.
