The Carmex MT7 solid carbide thread mill delivers precise M12 x 1 internal threads in through-holes with integrated through-coolant, tailored for CNC mill operators who demand reliability, accuracy, and longer tool life.

• Thread Size: Metric M12 x 1 internal thread milling capability for through-holes in metal workpieces
• Shank: MT7 compatible for secure, high-precision mounting on standard milling centers
• Material: Solid carbide for exceptional rigidity, wear resistance, and consistent thread quality
• Through-Coolant: Internal coolant bore delivers coolant directly to the cutting edge, aiding chip evacuation and cooling
• Geometry: Optimized flute and edge geometry designed specifically for reliable thread milling in metal

By delivering coolant through the bore, this tool minimizes chip buildup inside the threaded hole, reduces heat generation, and extends tool life—helping you maintain tight tolerances, finish threads cleanly, and shorten cycle times. It’s ideal for precision assemblies in automotive, aerospace, and general engineering applications where durable, accurate M12 x 1 threads are required in through-holes.
