Carmex Thread Mills Carbide Mini Type - UNJ (UNJC UNJF UNJEF UNJS) - 5/16, 3/8 x 24 - MT7

Carmex's Carbide Mini Type Thread Mill is a compact, high-speed tool built for UNJ threading in tight spaces. It handles UNJC, UNJF, UNJEF, and UNJS forms with a single MT7 shank, delivering precise internal and external threads in demanding applications.

• Thread forms: UNJ family compatibility — UNJC, UNJF, UNJEF, and UNJS threads can be produced with one versatile tool.
• Sizes: 5/16" and 3/8"-24 thread options, optimized for compact milling setups and clean, consistent thread profiles.
• Material and coating: Carbide MT7 grade with a sub-micron substrate and a TiAlN multi-layer coating (ISO K10–K20) for durability and wear resistance.
• Coating benefits: Triple-layer TiAlN coating reduces friction, extends tool life, and tolerates high-speed cutting in a range of materials.
• Flute design: Spiral flutes provide smooth cutting action; a short profile lowers cutting forces and improves stability; 3–5 flutes shorten machining time.
• Through-coolant: Coolant-through flutes enable efficient cooling and chip evacuation, especially beneficial for deep-hole threading.
• Hole depth and materials: Designed for deep-hole threading and capable of machining hardened materials up to 45 HRC.
• Versatility: The same tool can produce both external and internal threads, simplifying tooling and reducing setup changes.
• Shank and compatibility: MT7 Morse Taper shank fits a wide range of milling machines and holders, enabling quick tool changes.
• Performance: Medium to high cutting speeds, shorter machining times, and consistent thread quality across runs.

This thread mill is ideal for precision components in aerospace, automotive, mold-making, and general engineering projects where UNJ threads are required in tight or deep holes. Expect durable performance, reliable thread geometry, and efficient production with a tool designed to stay sharp longer and resist wear in demanding materials.
