Description

Carmex Thread Mills Carbide in the MTZ line delivers through-coolant directly to the cutting edge for precise threading through holes. Built for production environments, this M20 x 1.5 tool with an MT7 shank pairs robust carbide construction with an innovative cooling strategy to boost efficiency and consistency on demanding jobs.

  • Through-coolant flute design: Delivers coolant right to the cutting edge via flute channels for cooler cuts, reduced thermal distortion, and longer tool life.
  • Carbide construction: High-hardness carbide body provides stiffness and wear resistance for accurate, repeatable thread profiles.
  • Metric thread specification: Compatible with M20 x 1.5 thread requirements for reliable, standard-compliant threading.
  • MT7 shank: MT7 interface ensures solid tool seating and compatibility with a wide range of high-speed milling centers.
  • Through-hole threading optimization: Specifically designed for threading through holes with direct chip removal, minimizing scrap and improving cycle times.
  • Direct chip evacuation: Flute geometry facilitates efficient chip removal, reducing clogging and maintaining cut quality.
  • Versatile cooling compatibility: Effective on machines without external coolant systems, expanding the range of usable equipment in your shop.

This tool is ideal for job shops and production environments that require dependable through-hole threading with clean finishes, even when external coolant setup is limited. The combination of MTZ’s through-flute coolant delivery and the MT7 shank provides a stable, high-performance solution for precision thread milling in demanding applications, from automotive to aerospace components.
