Carmex Thread Mills Carbide Mini Type - UN (UNC UNF UNEF UNS) - 7/16 x 20 - MT7

The Carmex Carbide Mini Type Thread Mill is a compact, high-performance tool designed for precise internal and external threading across a wide range of UN thread standards. Built for shops and engineers who demand fast cycle times, reliable results, and long tool life in challenging materials.

• Thread forms supported: UN, UNC, UNF, UNEF, and UNS, enabling a single tool to cover multiple thread specifications.
• Size and shank: 7/16-20 thread size with MT7 shank for compatibility with common milling setups.
• Material and coating: Sub-micron MT7 carbide substrate with Titanium Aluminium Nitride (TiAlN) multi-layer coating (ISO K10–K20) for superior wear resistance.
• Flute design: Spiral flutes (3–5) that deliver smooth cutting action and efficient chip evacuation, plus through-flute coolant delivery for deep holes.
• Speed and efficiency: Optimized for medium to high cutting speeds, delivering shorter machining times thanks to a compact profile and multiple flutes.
• Deep-hole capability: Through-coolant and flute geometry facilitate threading in deep holes with reduced heat and improved surface finish.
• Versatility: One tool can produce a wide range of thread pitches and both internal and external threads, reducing tool changes.
• Durability: Special triple coating extends tool life and maintains edge integrity under demanding industrial conditions.
• Material hardness tolerance: Capable of threading in hardened materials up to 45 HRC, expanding its use in precision molds and hardened components.

This thread mill reduces downtime and improves consistency by combining high-speed performance with robust wear resistance. Its ability to thread deep features, handle diverse UN thread forms, and cut both internal and external threads with one tool makes it ideal for aerospace, automotive, mold making, and precision machining workflows where tight tolerances and reliable cycles matter most.
