Carmex Carbide Mini Thread Mills are compact, high-performance tools built for precision UNC/UNF/UNEF/UNS threading. Sized No.5 and No.6 x40 with MT7 shanks, they’re designed for high-speed, deep-hole threading across a range of hard materials.

• MT7 shank: Versatile shank compatible with a wide range of CNC toolholders for stable, reliable performance.
• Threading options: Handles UNC, UNF, UNEF, and UNS pitches, with the same tool capable of producing both internal and external threads.
• Sizes: No.5 and No.6 x40, optimized for small-diameter, precise thread milling in tight spaces.
• Carbide grade: MT7 sub-micron carbide with Titanium Aluminium Nitride multi-layer coating (ISO K10–K20) for enhanced wear resistance.
• Through-coolant: Coolant through the flutes enables efficient cooling and debris removal in deep holes.
• Flute design: Spiral flutes deliver smooth cutting action and effective chip evacuation.
• Multi-flute duration: 3–5 flutes shorten machining time while maintaining strong cutting edges.
• Durability: Special triple coating extends tool life under demanding high-speed conditions.
• Material capability: Suitable for machining hardened materials up to 45 HRC.

This tool combines versatility and efficiency: one mini thread mill can produce a wide range of thread pitches, cut both internal and external threads, and excel in deep-hole work thanks to through-coolant and a short profile that reduces cutting forces. The result is precise thread forms, shorter cycle times, and extended tool life, making it a reliable choice for automotive, aerospace, mold-making, and general precision manufacturing tasks.
