The Carmex Carbide Mini Thread Mills are precision threading tools engineered for machinists who need fast, accurate internal and external threads in tight spaces. Built for high-speed performance across a wide range of materials, these MT7 carbide mills deliver consistent results with outstanding tool life.

• Thread compatibility: UNC/UNF/UNEF/UNS standard threads—No. 6 × 32 for versatile alignment with common fasteners.
• Cutting material & coating: Sub-micron MT7 carbide with a Titanium Aluminium Nitride multi-layer coating (ISO K10–K20) for hardness and wear resistance.
• Coating durability: Special triple coating design extends tool life under demanding production conditions.
• Flute design: Spiral flutes provide smooth cutting action and efficient chip withdrawal, aiding precision in deep holes.
• Coolant delivery: Through-flutes coolant capability enhances heat removal in deep-hole applications, reducing thermal distortion.
• Machining speed & efficiency: Optimized for medium to high cutting speeds with a short profile that reduces cutting forces and shortens machining time.
• Versatility: A single tool that can produce a wide range of thread pitches and can cut both external and internal threads for flexible setups.
• Material compatibility: Suitable for general-purpose threading across many materials, including hardened steels up to 45 HRc.

These thread mills enable drilling and threading in challenging geometries and deep holes with less risk of broken taps, thanks to the short profile and robust coating. The ability to produce multiple thread forms and pitches with one tool simplifies workholding changes and inventory, while the through-coolant and high-speed capability help maintain precision and finish in production environments. Ideal for precision manufacturers in aerospace, automotive, and industrial sectors that demand reliable, long-lasting threading tools with consistent performance.
