The Carmex MTB Thread Mills are precision solid carbide tools designed for metric thread milling on CNC machines. Building on the MT line, the MTB family introduces through-bore coolant to improve chip evacuation and extend tool life, delivering reliable internal threading for demanding engineering applications.

• Through-Coolant Bore: coolant is supplied through the tool bore directly to the cutting zone, promoting continuous chip evacuation and effective cooling for cleaner threads.
• Solid Carbide Construction: high rigidity and wear resistance ensure accurate thread form and long-lasting performance in tough materials.
• MT7 Interface: compatible with standard MT7 tool holders for secure, precise seating and dependable repeatability in automated setups.
• Metric Thread Range: optimized for M8 x 1.25 and M10 x 1.25 internal threads, delivering consistent pitch accuracy and clean thread profiles.
• Optimized Thread Milling Geometry: specially engineered flute and land geometry to produce smooth, defect-free threads with minimal finishing.
• Durability and Life: the combination of through-coolant cooling and robust carbide extends tool life and reduces total tooling costs over time.

By enabling coolant through the bore, this tool reduces heat buildup and chip packing inside the threaded hole, leading to improved surface finish, fewer reworks, and lower maintenance downtime. It’s ideal for precision components in automotive, aerospace, hydraulics, and general mechanical engineering where reliable internal threads and repeatable results matter. The Carmex MTB thread mill—with MT7 compatibility and through-coolant benefits—helps you achieve accurate threads, longer tool life, and consistent production performance in one robust solution.
