Description

Introducing the Carmex MTZ thread mill: a carbide, through-coolant tool engineered for precise through-hole threading. Designed for MT7 holders and G1/8 x 28 threads, it delivers coolant directly through the flutes to the cutting edge for consistent, high-quality threads.

  • Through-Coolant Flute Delivery: Coolant is channeled through the flutes to the cutting edge, improving heat control and chip evacuation for cleaner threads.
  • 55° G-Thread Form: 55-degree thread geometry (G-style) provides accurate engagement and robust thread form in metallic workpieces.
  • G1/8 x 28 Thread Size: Optimized to produce precise G1/8 x 28 threads on through-holes with reliable repeatability.
  • MT7 Shank: Stable MT7 shank compatibility ensures rigid seating in standard CNC toolholders for consistent milling performance.
  • Solid Carbide Construction: Premium carbide offers superior hardness and wear resistance for longer tool life in demanding materials.
  • Direct Chip Removal for Through-Hole Machining: Flute geometry supports efficient chip clearance, reducing clogging and potential burrs on through-hole threads.
  • Machine-Friendly Without External Coolant: Effective cooling and cutting performance even on systems without an external coolant supply, enhancing versatility in workshop setups.

The Carmex MTZ through-coolant thread mill is built to deliver dependable threading results where through-holes and coolant access are critical. Expect clean thread profiles, reduced heat-related distortion, and improved productivity thanks to direct cooling and efficient chip removal. Ideal for shops manufacturing components requiring G1/8 x 28 threads, from aerospace and automotive to general precision machining, this tool pairs robust carbide performance with practical, real-world usability.
