Carmex Thread Mills Carbide Drill Mill - Metric - M8 x 1.25 - MT7

The Carmex MTD Thread Mill is a precision carbide drill-mill designed to drill, chamfer, and thread mill M8 x 1.25 holes in a single operation, delivering consistent results in high‑volume production. Built for reliability, this tool simplifies setups and reduces cycle times without compromising thread quality.

• All-in-one operation: Drills, chamfers, and threads in one pass to cut cycle times and minimize tool changes.
• Two-fluted design: Balanced cutting action with efficient chip evacuation for steady performance.
• 45° chamfer: Pre-formed chamfering for easy start and clean, accurate thread engagement.
• Internal coolant bore: Directs coolant to the cutting edges, lowering heat and extending tool life.
• MT7 shank: Robust interface for rigid, high-speed milling in a variety of machines.
• Right- and left-hand internal threads: Versatile threading capability for both directions without changing tools.
• Blind and through-hole compatibility: The same tool handles both hole types, simplifying manufacturing workflows.
• Sub-Micron carbide with PVD triple coating: Combines exceptional hardness and toughness with smooth cutting and long life.

By consolidating drilling, chamfering, and threading into one operation, the tool delivers reliable, repeatable thread quality with high surface finish. The MT7 interface ensures stable performance at speed, while the internal coolant bore supports deep holes and demanding materials. Ideal for mass production of threaded holes in metal components across automotive, aerospace, and precision engineering applications, it helps manufacturers improve throughput and consistency without sacrificing accuracy.
