Description

The Carmex MT7 M5 x 0.8 Thread Mill is a precision carbide tool designed to drill, chamfer, and thread mill internal holes in a single pass, ideal for high-volume production environments. It delivers consistent hole quality with fewer tool changes, making it perfect for automated or semi-automatic machining setups.

Carmex Thread Mills Carbide Drill Mill - MT7

  • All-in-one operation: Drills, chamfers, and thread mills in one pass to reduce cycle times and eliminate intermediate tool changes.
  • Two-fluted design: Balanced geometry for stable cutting, efficient chip formation, and clean thread surfaces.
  • 45° chamfer: Precise entry chamfer that supports reliable thread formation in mass production.
  • Metric threading: M5 x 0.8 thread specification, suitable for standard metric hole applications; accommodates both right- and left-hand internal threads.
  • MT7 Sub-Micron carbide with PVD triple coating: Hard, tough carbide core paired with a low-friction, durable coating for smooth cutting and extended tool life.
  • Internal coolant bore: Built-in coolant channel to improve chip evacuation, cooling, and surface finish.
  • Blind and through hole versatility: One tool handles both blind and through holes without needing substitutions or changes.
  • MT7 interface readiness: Designed for compatibility with MT7 tooling systems, ensuring secure fit and reliable performance in standard CNC setups.

By uniting drilling, chamfering, and thread milling into a single operation, this tool minimizes production bottlenecks and enhances hole quality. The 45° entry, combined with the two-fluted geometry, delivers consistent thread starts and smooth internal surfaces. The internal coolant bore and high-performance MT7 carbide with PVD coating maximize life and uptime, making the Carmex Thread Mill a dependable choice for high-speed, high-precision threading in both blind and through-hole applications.
