Carmex MTB through-coolant thread mills are engineered for precision NPT threading with an MT7 shank, delivering reliable performance in demanding materials. This solid carbide tool combines a robust cutting core with an innovative coolant-through-bore design to keep chips moving freely and temperatures in check.

• Through-Coolant Bore: coolant is delivered directly through the tool to flush chips and cool the cutting edges, enhancing stability and surface finish.
• Solid Carbide Construction: a rigid, heat-resistant substrate that maintains accuracy and extends tool life in tough metals.
• MT7 Shank: compatible with standard MT7 toolholders for secure, rigid mounting and repeatable performance.
• NPT Thread Milling Capability: specifically designed to cut internal NPT threads with consistent form and tolerance.
• Size — 2 1/2" Diameter × 8" Length: precise dimensional footprint suited for manufacturing environments requiring larger-diameter NPT threads.

This MTB tool is ideal for applications like pipe fittings, hydraulic and pneumatic components, and other assemblies that demand accurate internal NPT threads. The through-coolant feature reduces heat buildup and chip packing, enabling deeper cuts, cleaner thread profiles, and longer tool life—ultimately lowering cycle times and part rejection rates. In comparison to traditional flood-cooled or dry milling approaches, this design offers improved chip evacuation, better surface integrity, and greater uptime in high-demand production environments. For shops focusing on precision threading with robust, long-lasting tooling, this Carmex MTB MT7 through-coolant thread mill delivers dependable performance and measurable efficiency gains.
