Carmex Carbide Mini Thread Mills are a compact, high-precision threading solution designed for engineers and machinists who demand reliable internal and external threads in tight spaces and across a range of materials. Built for deep-hole applications and high-speed machining, these MT7-coated tools deliver consistent results with minimal downtime.

• Size options: No. 2 and No. 3 thread mills with a 56 mm length for versatile threading in compact setups.
• Coating and grade: MT7 sub-micron carbide with a Titanium Aluminium Nitride multi-layer coating for extended tool life and corrosion resistance.
• Thread compatibility: Capable of producing UN, UNC, UNF, UNEF, and UNS thread forms, usable for both internal and external threads.
• Through-coolant: Coolant-through flutes enhance heat removal in deep-hole threading, improving dimensional accuracy and tool longevity.
• Flute design: Spiral flutes provide a smooth cutting action and help evacuate chips efficiently, reducing built-up edge.
• Cutting performance: Optimized for medium to high cutting speeds to minimize cycle times without sacrificing thread quality.
• Profile and efficiency: Short profile lowers cutting forces, reducing the risk of breakage and enabling faster machining in challenging depths.
• Material capability: Effective for hardened materials up to 45 HRC, expanding usability across tough workpieces.
• Versatility: A single tool can cover a wide range of thread pitches and both external and internal threads, simplifying tooling inventory.
• Coating durability: Triple-layer coating contributes to longer tool life under demanding threading conditions.

This mini thread mill is ideal for precision threading in molds, aerospace fixtures, automotive assemblies, and hydraulic components where space is limited and parts demand tight tolerances. The combination of through-coolant, spiral flutes, and a robust MT7 carbide substrate ensures clean starts, accurate thread profiles, and reliable performance when machining difficult materials. By consolidating multiple thread options into one versatile tool, it helps reduce setup changes, cycle times, and overall production costs while maintaining high-quality thread precision.
