The Carmex MTB Solid Carbide Thread Mill with Through Coolant is built for precision internal threading in CNC mills, delivering consistent UNC, UNF, UNEF, and UNS threads with extended tool life. Designed for shops and engineers who demand reliable performance, chip control, and long-lasting cutting power.

• Through-Coolant Bore: coolant is delivered directly through the tool bore to the cutting edges, enabling efficient chip evacuation in deep holes and reducing heat buildup.
• Solid Carbide Construction: a tough, heat-resistant material that maintains sharpness and rigidity for precise thread profiles across many materials.
• MT7 Shank: robust Morse Taper 7 shank for secure, stable mounting on compatible milling centers and automatic tool changers.
• Thread Form Compatibility: engineered to reliably create internal threads in UNC, UNF, UNEF, and UNS forms with tight tolerances.
• Dimensions: 0.75" diameter with a 10" overall length, suitable for deep-hole and through-hole threading work.
• Precision Geometry: optimized flute and cutting-edge geometry balance chip control, surface finish, and dimensional accuracy for repeatable results.

This MTB thread mill with through-coolant delivers measurable benefits: cleaner chip removal reduces the risk of re-cutting and built-up edge, while effective cooling extends tool life and stabilizes thread quality. It’s especially advantageous for automotive, hydraulic, and aerospace components where dependable internal threads and consistent finishes matter. Use it to streamline threading operations, minimize downtime, and achieve repeatable, high-quality results in challenging materials.
