Carmex Thread Mills Carbide Mini Type MT7 are precision-engineered tools designed for fast, reliable metric threading in a wide range of materials. Ideal for machinists and production environments, they deliver consistent results in both internal and external threads, especially in deep-hole applications.

• Material and coating: Carbide MT7 sub-micron grade with a TiAlN multi-layer coating (ISO K10–K20) for outstanding wear resistance and longer tool life.
• Thread compatibility: Precision tooling for metric threads M6 and M7 with 0.5 mm pitch, usable for both external and internal threads.
• High-speed performance: Optimized for medium to high cutting speeds, enabling faster machining with reduced cycle times.
• Short profile advantages: Shorter geometry lowers cutting forces and improves stability, reducing the risk of deflection and chatter.
• Coolant flow through flutes: Through-flute coolant enhances chip evacuation and cooling in deep-hole threading for cleaner threads and longer tool life.
• Flute design: Spiral flutes provide smooth cutting action and effective chip management, even in challenging materials.
• Multi-flute efficiency: 3–5 flutes shorten machining time while maintaining thread accuracy and surface finish.
• Material versatility: General-purpose threading capable of handling a wide range of materials, including hardened steels up to 45 HRc.
• Reliability for deep holes: Specifically advantageous for drilling and threading in deep holes without frequent tool changes.
• Longer tool life: Triple coating and refined geometry contribute to extended life, reducing replacement costs and downtime.

These MT7 mini thread mills offer a practical, high-performance solution for precise, repeatable threading in compact setups. Whether you’re producing concise fasteners or preparing critical components, this tool delivers deep-hole threading capability, versatility across thread pitches, and dependable results in demanding materials.
