Carmex Thread Mills Carbide Mini Type No. 3 x 80 MT7 is a compact, high‑performance thread milling tool designed to cut both internal and external UN threads (UNC, UNF, UNEF, UNS) with a single, versatile insert. Built for precision work, it delivers fast, reliable threading in a range of materials.

• Threading capability: Handles internal and external UN threads (UNC, UNF, UNEF, UNS) with one tool, reducing tooling changes and setup time.
• Size and geometry: No. 3 x 80 with a short profile for strong, stable cutting and excellent control in confined cavities.
• Material and coating: Carbide MT7 sub‑micron grade with a multiple TiAlN coating (ISO K10–K20) for outstanding wear resistance at speed.
• Flute design: Spiral flutes (3–5 flutes) provide smooth cutting action and efficient chip evacuation, especially in deep holes.
• Performance: Optimized for medium to high cutting speeds, delivering shorter machining times and reduced cutting forces due to the compact profile.
• Deep‑hole capability: Coolant through the flutes and a short profile enable effective threading in deep holes with minimal tool chatter.
• Material hardness: Suitable for machining hardened materials up to 45 HRC, expanding the range of applications from alloys to hardened steels.
• Durability: Triple coating and precision engineering translate to longer tool life and consistent performance over many cycles.

This tool is ideal for shops needing fast, reliable thread milling for complex parts, from connectors and hydraulic components to aerospace fasteners. Its ability to produce multiple thread pitches with a single tool, combined with deep‑hole threading capability and robust wear resistance, makes it a practical choice for high‑volume production or tight tolerance work. Whether you’re replacing taps in challenging holes or seeking precision threads without tapping risk, this MT7 carbide mini thread mill delivers consistent, accurate results.
