The Carmex Thread Mills Carbide with Through Coolant is a precision threading solution designed for through-holes, delivering reliable, high-quality threads with minimal setup. Built for metric threads M10 and M12 x 1.5, it uses a robust MT7 shank to fit a wide range of CNC machines and holders.

  • Through-coolant flute design: coolant is delivered directly through the flutes to the cutting edge for effective heat management and consistent cutting performance.
  • Metric thread options: supports M10 and M12 x 1.5 threading in through-holes, enabling standard, common thread sizes in a single tool.
  • Carbide construction: premium carbide geometry provides stiffness, wear resistance, and long tool life under demanding threading operations.
  • MT7 shank: compatible with a broad range of toolholding systems for solid rigidity and precise alignment in the spindle.
  • Direct chip evacuation for through-holes: optimized flute design promotes smooth chip removal, reducing clogging and improving threading consistency.
  • Optimized flute geometry: engineered to balance cutting forces, improve surface finish on threaded features, and minimize burr formation.
  • No external coolant dependency: through-tool cooling makes it effective even on machines without dedicated external coolant systems.

By delivering cooling to the cutting edge and ensuring efficient chip evacuation, this thread mill supports stable, accurate threads with fewer passes and lower cycle times. The through-coolant design helps extend tool life and maintains thread quality across steel, stainless steel, and aluminum workpieces. Ideal for automotive, aerospace, mold making, and general precision machining where reliable through-hole threading is essential, the Carmex MT7-based tool delivers consistent performance in everyday production environments.
