The Carmex Thread Mills Carbide Drill Mill is a high‑efficiency solution for drilling, chamfering, and thread milling in a single operation. Designed for mass production environments, it delivers precise UNC/UNF/UNEF/UNS internal threads with consistent quality from first part to last.

• Two-fluted drill/thread milling cutter: Optimized geometry for simultaneous drilling and thread milling with clean, predictable chip formation.
• 45° chamfer: Easy thread start and improved thread engagement, reducing setup time and finishing passes.
• Internal coolant bore: Integrated coolant channel aids cooling and chip evacuation for smoother cuts and longer tool life.
• MT7 sub‑micron carbide with PVD triple coating: Combines exceptional hardness and toughness with a low-friction, wear‑resistant surface for high performance.
• Right- and left‑hand internal threads: Flexibility to machine both orientations without tool changes, expanding application versatility.
• Compatible with blind and through holes: One tool handles a variety of hole depths, eliminating the need for multiple tools.
• Mass production ready: Reduces cycle times by combining drilling, chamfering, and threading into one operation, cutting setup and handling time.
• Pack of 24: Economical quantity for consistent supply on busy production floors.

This carbide thread mill is purpose-built for demanding applications where precision thread quality matters as much as throughput. Use it to streamline CNC holemaking in automotive, aerospace, and general manufacturing tasks, where you need reliable internal threads in UN standards while maintaining tight tolerances and smooth surface finish. The tool’s robust coating and substrate design help resist wear in tougher materials, ensuring repeatable results across long production runs.
