Carmex MTB Thread Mills in Solid Carbide with Through Coolant deliver precise internal threads in through-holes, engineered for professionals who demand durability, accuracy, and productivity in machining centers using MT7 shanks. Specifically designed for UNC/UNF/UNEF/UNS thread formats, this tool elevates through-hole threading with reliable performance.

• Through-Coolant Bore: Coolant is delivered through the bore during cutting, enabling efficient chip evacuation and superior cooling in deep or complex holes.
• Thread Milling Capability: Internal thread milling for UNC/UNF/UNEF/UNS formats, including 1/4-28, suitable for a wide range of materials and applications.
• Solid Carbide Construction: High-hardness carbide body provides rigidity, wear resistance, and long tool life under demanding cutting conditions.
• MT7 Shank: Designed to fit MT7 spindle tooling for secure, accurate alignment and repeatable performance on compatible machines.
• Compact Cutting Geometry: Precisely engineered geometry to produce clean, accurate threads with smooth finish in through-holes.

The through-coolant design minimizes chip buildup and heat, enabling higher cutting speeds and more consistent thread quality. With the durability of solid carbide, these MTB thread mills resist wear in tough materials, reducing tool changes and lowering overall operating costs. Ideal for precision engineers and shops aiming for reliable, repeatable internal threads in a variety of modern metalworking projects.
