The Carmex Carbide Mini Thread Mill MT7 is a compact, high-performance threading tool designed for precision internal and external threads in tight spaces. Built for machinists who demand speed, accuracy, and durability, it excels in deep-hole threading and hardened materials.

• Threading versatility: Produces a wide range of threads and pitches with a single tool, enabling both internal and external threads without swapping tools.
• Size and fit: Metric size M2.5 x 0.45 with MT7 shank, ideal for small-diameter thread milling.
• Carbide MT7 with TiAlN coating: Sub-micron carbide grade MT7 with a Titanium Aluminum Nitride multi-layer coating (ISO K10–K20) for wear resistance and long tool life.
• Deep-hole capability: Through-flute coolant and a short profile support threading in deep holes with effective chip evacuation.
• Coating durability: Triple-layer coating design extends tool life under high-speed, high-load conditions.
• Flute design: Spiral flutes ensure smooth cutting action and efficient kerf formation, while 3–5 flutes shorten machining time.
• Material compatibility: General purpose for all materials and capable of machining hardened materials up to 45 HRC.
• Performance at speed: Optimized for medium to high cutting speeds with lower cutting forces thanks to the short profile.

By consolidating multiple threading tasks into a single carbide tool, it reduces setup time and tool changes while delivering consistent thread quality. The MT7 mini thread mill is well-suited for precision assemblies, small-diameter fasteners, and applications where deep, accurate threads are required in hard metals. Expect reliable performance, longer tool life, and cleaner thread finishes even in challenging materials and geometries.
