Carmex Thread Mills Carbide Drill Mill - UN (UNC UNF UNEF UNS) - x 16 - MT7

The Carmex MTD Thread Mill combines drilling, chamfering, and threading into a single operation for machinists producing UN thread forms. Built for high-volume work, this carbide tool reduces the number of steps required to create internal threads while maintaining reliable surface quality.

• Single-Pass Operation: Drills, chamfers at 45°, and mills threads in one continuous cycle, eliminating separate tool changes.
• Two-Fluted Design: Provides stable cutting action with an integrated 45° chamfer for clean entry and consistent thread starts.
• Internal Coolant Bore: Delivers coolant directly to the cutting zone to support longer tool life during extended runs.
• MT7 Carbide Substrate: Sub-micron grade carbide with PVD triple coating offers a balance of hardness and toughness for smooth performance on various materials.
• Thread Versatility: Handles right-hand and left-hand internal threads in both blind and through holes for UNC, UNF, UNEF, and UNS profiles at the specified size.

This approach shortens cycle times in mass production environments and helps shops maintain high thread quality without additional finishing steps. By consolidating three operations into one tool, users reduce setup time and tooling inventory while achieving repeatable results on standard CNC equipment.
