Carmex Thread Mills Carbide Mini Type MT7, metric size M1.4 x 0.3, is a compact high‑performance threading tool designed for precise internal and external threads in tight spaces and across a wide range of materials.

• Carbide grade and coating: MT7 sub‑micron carbide with a TiAlN multi‑layer coating (ISO K10–K20) for exceptional wear resistance and high‑temperature stability.
• Shank and compatibility: MT7 Morse taper shank for secure, reliable mounting in compatible spindles.
• Threading range: Produces a wide range of threads and pitches with a single tool, including the M1.4 x 0.3 specification.
• Internal and external threads: One tool can machine both internal and external threads, reducing setup time and tooling variety.
• Through‑coolant: Coolant through the flutes delivers effective cooling and chip evacuation, especially valuable for deep holes.
• Flute design: Spiral flutes provide a smooth cutting action, while the short profile lowers cutting forces and helps prevent broken taps.
• Through‑hole performance: Optimized for deep hole threading, enabling access to challenging geometries.
• Productivity: Multi‑flute configuration (3–5 flutes) shortens machining time and, with the special triple coating, extends tool life.
• Material capability: Suitable for high‑speed machining and capable of cutting hardened materials up to 45 HRc.

This tool is ideal for precision threading tasks in tight cavities, aerospace components, mold bases, and small‑diameter fastener holes where deep, accurate threads are required. It delivers reliable performance at medium to high cutting speeds, reduces the need for tool changes, and maintains consistent thread quality across a range of pitches and both external and internal threads. With through‑coolant and a robust MT7 interface, you’ll experience longer tool life and fewer interruptions in demanding applications.
