The Carmex Thread Mills Carbide Mini Type is a compact, high‑performance threading solution designed for through‑coolant operations on UNJ family threads (UNJC, UNJF, UNJEF, UNJS). Sized at 7/16 x 14, it delivers precise threads at high speeds with versatility across internal and external features.

• Thread forms supported: UNJ, UNJC, UNJF, UNJS for broad compatibility with common aerospace and precision components.
• Size and pitch: 7/16" major diameter with 14 threads per inch (7/16 x 14).
• Material and coating: Carbide MT7 grade with a sub‑micron finish and a TiAlN multi‑layer coating (ISO K10–K20) for superior hardness and heat resistance.
• Coating durability: Special triple coating enhances tool life in demanding, high‑speed applications.
• Flute design: Spiral flutes with 3 to 5 cutting edges provide smooth cutting action and reduced machining time.
• Through‑coolant capability: Coolant through the flutes enables efficient heat removal and chip evacuation, especially in deep holes.
• Deep‑hole performance: Engineered to excel in deep‑hole threading where conventional tools struggle, with reliable chip flushing and cooling.
• Machining hardened materials: Capable of machining materials up to 45 HRc, expanding use in tough, high‑hardness parts.
• Reliability in production: Short tool profile lowers cutting forces and reduces the risk of broken taps, improving uptime in busy shops.
• Versatility: A single tool can produce a wide range of thread pitches and both external and internal threads without swapping tools.

Designed for operators who demand consistent thread quality, the Carmex MT7 mini thread mill delivers precise results at high speeds while minimizing cycle times. Its through‑coolant design and multi‑edge geometry help achieve clean starts, tight tolerances, and longer tool life in challenging materials. Ideal for production environments such as aerospace fastener fabrication, automotive components, hydraulic manifolds, and precision machinery where durable threading in hard or exotic materials is required.
