The Carmex MTB solid carbide thread mill with through coolant is built for precision-focused shops that manufacture metric threads, starting with M4 x 0.7. Designed to deliver clean threads with reliable cooling, it ensures smooth operations from first cut to the final finish.

• Through-Coolant Bore: coolant is delivered through the tool to the cutting edge, improving chip evacuation and helping maintain a stable cutting zone.
• Solid Carbide Construction: high-hardness carbide provides wear resistance and consistent thread profiles even in demanding metals.
• MT7 Shank: Morse Taper 7 interface offers robust seating and reduced runout for precise threading in challenging setups.
• Metric Thread Size: engineered for M4 x 0.7 internal threads with tight pitch control and accurate thread form.
• Thread Milling Geometry: optimized geometry supports clean, burr-free finishes and stable feeds during small-diameter thread milling.
• MTB Line Innovation: adds cooling-through-bore capability to extend tool life and improve machining reliability across jobs.

This combination of through-coolant efficiency, durable carbide construction, and precise MT7 mounting makes it ideal for high-precision small-thread applications in metalworking. It minimizes heat-related wear, reduces chip buildup in deep or tight holes, and helps you achieve consistent thread quality across multiple parts and setups.
