Carmex Carbide Thread Mills Mini Type is a high-precision metric threading tool designed for tight spaces. Built for machinists who need reliable internal and external threads in deep-hole work, its long MT7 shank and advanced coating deliver fast, accurate results with a durable edge.

• Thread size and pitch: M2.5 x 0.45 for standard metric threading
• Shank and reach: MT7 long-shank design with an 8 mm reach for access in deep holes
• Material and coating: Carbide grade MT7 with a sub-micron finish and Titanium Aluminium Nitride multi-layer coating (ISO K10–K20) for extended tool life
• Cutting performance: Optimized for medium to high cutting speeds with low cutting forces due to a short profile
• Hole threading capabilities: Through-flute coolant enhances cooling and chip evacuation in deep-hole threading; spiral flutes ensure smooth cutting action
• Versatility: A single tool capable of producing a wide range of threads and pitches and cutting both internal and external threads
• Durability and life: Triple coating increases wear resistance, enabling machining of hardened materials up to 45 HRc
• Flute design and efficiency: 3–5 flute configuration reduces machining time and improves chip removal

This thread mill is built to shorten cycle times, cut deeper with confidence, and reduce the risk of tap breakage in challenging applications. It’s ideal for precision components across industries like automotive, electronics, and aerospace, where consistent thread quality and tool longevity matter most. Use it for fast, reliable threading in hard materials and tight geometries, without the need to switch tools for different thread ranges.
