Carmex Thread Mills Carbide Mini Type - Metric - M4.5, M5 x 0.75 - MT7

The Carmex Thread Mills Carbide Mini Type is a compact, high‑precision metric thread mill designed for internal and external threads (M4.5 and M5 x 0.75) with an MT7 shank. Built for hard materials and high‑speed machining, it delivers consistent threads with minimal downtime.

• Tool material and coating: Carbide with MT7 sub‑micron grain and a Titanium Aluminium Nitride multi‑layer coating (ISO K10‑K20) for long life and wear resistance.
• Shank and size: MT7 shank compatible with standard CNC tooling; supports metric threads M4.5 and M5 x 0.75 with a single miniature tool.
• Flute geometry: Spiral flutes (3–5) provide smooth cutting action and efficient chip evacuation, especially in deep holes.
• Coolant through design: Through‑the‑flute coolant enhances cooling and flushing in deep hole applications, reducing heat and chip buildup.
• Depth and versatility: Enables machining in deep holes and can produce a wide range of thread pitches with the same tool, for both internal and external threads.
• Cutting speeds and efficiency: Optimized for medium to high cutting speeds, delivering shorter machining times and lower cutting forces thanks to the short profile.
• Material capability: Suitable for hardened materials up to 45 HRc, expanding the range of workpieces you can thread without changing tools.
• Durability: Special triple coating contributes to longer tool life and reliable performance under demanding conditions.

Designed for professionals who demand precision and efficiency, this mini thread mill reduces the risk of broken taps, lowers cycle times, and delivers repeatable thread quality across a broad range of pitches. Whether threading in deep bores or finishing tight sockets, the Carmex MT7 mini thread mill helps you complete jobs faster with confidence.
