The Carmex Carbide Mini Thread Mill MT7 is a compact, high-performance threading tool designed for metric M2 x 0.4 threads. It excels in tight spaces while delivering precise internal and external threads with efficient, high-speed machining.

• Thread size: Metric M2 x 0.4 threading capability for small-diameter projects
• Material and coating: MT7 sub-micron carbide with a titanium aluminium nitride multi-layer coating (ISO K10–K20)
• Cutting speeds: Optimized for medium to high cutting speeds to shorten cycle times
• Profile: Short tool profile reduces cutting forces and lowers the risk of tap damage
• Flute design: Spiral flutes (3–5) provide smooth cutting action and efficient chip evacuation
• Coolant through flutes: Through-flute coolant improves cooling and lubrication in deep-hole threading
• Versatility: One tool can produce a wide range of thread pitches and both external and internal threads
• Material capability: Suitable for machining hardened materials up to 45 HRc
• Durability: Special triple coating extends tool life and maintains performance over time

This mini thread mill enables deep-hole threading with efficient coolant flow, delivering consistent thread quality across a variety of materials. Its short profile and multi-flute design translate to faster cycles, lower cutting forces, and longer tool life, reducing downtime and tool changes. Ideal for precision threading in automotive, moldmaking, and general engineering applications where compact, reliable threading in confined spaces is essential.
