Carmex Thread Mills Carbide Mini Type - UN (UNC UNF UNEF UNS) - No. 5, No. 6 x 40 - MT7

Carmex Carbide Mini Thread Mill is a compact, high-performance tool designed for precise UN-threading across a range of materials. With a durable MT7 shank and a coating engineered for speed, it’s built for shops that demand versatility, reliability, and efficient deep-hole threading.

• Coating and material: MT7 sub-micron carbide with a titanium aluminum nitride multi-layer coating (ISO K10–K20) for enhanced wear resistance and heat tolerance at higher cutting speeds.
• Thread forms supported: Compatible with UN family threads, including UNC, UNF, UNEF, and UNS, covering common aerospace, automotive, and mechanical assemblies.
• Size and geometry: No.5 and No.6 thread diameters, 40 mm overall length, MT7 shank; spiral flutes (3–5) provide smooth cutting and efficient chip evacuation.
• Cooling and deep-hole capability: Through-flutes allow coolant to reach the cutting zone, delivering effective cooling in deep holes for consistent thread quality.
• Performance: Optimized for medium to high cutting speeds; short profile reduces cutting forces and minimizes the risk of tap breakage; able to machine hardened materials up to 45 HRC.
• Versatility: A single tool capable of producing a wide range of thread pitches and both internal and external threads, simplifying tooling and setup.
• Durability and reliability: Triple-layer coating and precise geometry extend tool life, supporting longer production runs with fewer tool changes.

This thread mill delivers dependable, high-precision threading in challenging features and tight tolerances. Its combination of high-speed capability, deep-hole performance, and broad thread compatibility makes it a practical choice for precision manufacturing, aerospace fittings, automotive components, and general engineering use where threaded connections must perform under demanding conditions.
