The Carmex Thread Mills Carbide Mini Type is a compact, high-precision threading tool designed for both internal and external threads in tight spaces. With a 1/4 x 20 UNC thread capability, MT7 shank, and a 19 mm reach, it’s built for versatile, fast threading in challenging workpieces.

• Thread types supported: Internal and external threads in UNC/UNF/UNEF/UNS formats, specifically 1/4-20 size.
• Shank and reach: MT7 shank for strong, accurate mounting; 19 mm reach to access deep cavities.
• Carbide grade and coating: Sub-micron MT7 carbide with a titanium aluminium nitride multi-layer coating (ISO K10–K20) for exceptional wear resistance at speed.
• Durability: Triple coating technology extends tool life in demanding materials and high-speed applications.
• Flute design: Spiral flutes deliver smooth cutting action and efficient chip evacuation; coolant-through flutes enhance performance in deep holes.
• Number of flutes: 3–5 flutes for faster material removal and shorter machining times without sacrificing thread quality.
• Depth capability: Optimized for deep-hole threading, enabling reliable threading in challenging geometries.
• Material capabilities: Suitable for a broad range of materials and capable of machining hardened materials up to 45 HRc.
• Performance characteristics: Tailored for medium-to-high cutting speeds with a short profile that reduces cutting forces and helps prevent tapping issues.

This tool delivers precise, repeatable threads in tight-featured parts, with efficient heat management and chip control that keep thread quality consistent across a wide range of pitches. Its compact design and through-coolant capability make it a reliable choice for aerospace brackets, automotive housings, hydraulics, and other precision components where space is limited and thread integrity matters.
