Description

The Carmex MTZ carbide thread mill with through-coolant is engineered for through-hole threading, delivering coolant directly to the cutting edge for precise, efficient results. It’s ideal for shops needing reliable performance even on machines without an external coolant supply.

  • Through-coolant delivery through flute channels: Coolant is guided along the flute to the cutting edge, enabling controlled cooling and efficient chip evacuation during threading.
  • Carbide construction: Premium carbide substrate provides high hardness and wear resistance for long tool life in demanding threading operations.
  • Flute geometry optimized for through holes: Specialized flute shape supports direct chip removal and clean thread formation in through-holes.
  • Metric thread size: M20 x 2.5 thread form for precise threading in standard metal components.
  • MT7 shank: Secure MT7 tool holder compatibility ensures stable, vibration-free performance at high speeds.
  • Designed for machines without external coolant: Effective cooling without reliance on external coolant lines, increasing versatility in diverse machining setups.

By delivering coolant exactly where it’s needed, this thread mill maintains lower cutting temperatures, reduces tool wear, and produces consistent thread quality. The through-hole–focused design promotes direct chip removal, minimizing rework and improving cycle times. With the MTZ carbide construction and robust geometry, you can achieve smooth thread finishes and tight tolerances, making it a dependable choice for precision threading in automotive, moldmaking, and general engineering applications. The MT7 shank offers secure, reliable performance on machines with limited coolant infrastructure, expanding your threading capabilities in tighter production environments.
