Designed for precision threading in challenging materials, the Carmex Thread Mills Solid Carbide with Through Coolant delivers reliable UNC/UNF/UNEF/UNS thread engagement with every pass. Built for machinists who demand consistency and tool longevity, this MTB-style thread mill combines robust carbide durability with an integrated through-coolant path to keep cutting edges cool and chips moving.

• Through-Coolant Bore: Coolant is fed through the tool to the cutting edge, improving chip evacuation and reducing heat buildup for cleaner hole walls.
• Solid Carbide Construction: High-hardness carbide provides exceptional wear resistance and stable, repeatable thread profiles over many cycles.
• MT7 Shank: Engineered with an MT7 interface for rigid, precise seating in compatible CNC spindles, ensuring concentric threading and minimal runout.
• Thread Forms Supported: Optimized for UN, UNC, UNF, UNEF, and UNS thread standards, enabling versatile use across multiple projects.
• Size: 9/16 in cutting diameter with a 12 (overall) length, designed to tackle deeper or longer-threading applications without frequent tool changes.

This through-coolant thread mill is ideal for high-precision internal threads in molds, aerospace components, automotive parts, and other applications where tight tolerances and clean thread valleys matter. By improving chip evacuation and cooling, it reduces thermal wear, extends tool life, and helps maintain consistent thread quality even in demanding materials. Whether you’re creating new threads or finishing existing ones, this Carmex MTB solid carbide tool is built to deliver reliable performance and sustained value in your machining workflow.
