Carmex MTB solid carbide thread mills with through-coolant are designed for precise internal threading in through-holes, accommodating UNC, UNF, UNEF, and UNS thread types. Built for durability and dependable performance, these MT7-shank tools support No. 8, No. 10, and No. 12 threads with a 32 mm length, delivering clean, repeatable threads you can trust.

• Through‑coolant bore: delivers cutting fluid directly to the cutting edge for efficient chip evacuation and consistent cooling, reducing heat buildup and extending tool life.
• Solid carbide construction: premium carbide substrate provides high hardness and wear resistance for longer tool life in demanding materials.
• MT7 shank: robust, compatible shank design for rigid, vibration-free performance on a wide range of machines.
• Thread sizes: suitable for No. 8, No. 10, and No. 12 internal threads with a 32 mm length, optimized for precise engagement and accurate pitch.
• Thread milling geometry: optimized flute and cutting-edge geometry engineered to produce smooth thread profiles with minimal burrs and excellent surface finish.

These MTB thread mills excel in applications where through-holes must be threaded with tight tolerances and reliable chip control. They are ideal for manufacturing components in aerospace, automotive, mold making, and precision engineering, where consistent thread quality and tool longevity drive productivity and cost efficiency. Use cases include internal threaded holes in aluminum or steel parts, deep pockets requiring effective coolant delivery, and setups that benefit from clean, burr-free thread profiles on every hole.
