Carmex MTB solid carbide thread mill with through coolant is built for precision threading in UN, UNC, UNF, UNEF, and UNS holes. Designed for demanding metalworking environments, it combines tough carbide construction with an innovative bore coolant design to improve chip evacuation and extend tool life.

• Through-Coolant Bore: Coolant is channeled directly through the tool to the cutting edge, flushing chips from deep holes and reducing heat buildup during threading.
• Solid Carbide Construction: Delivers high rigidity, exceptional wear resistance, and long-lasting performance in tough threading applications.
• Diameter × Length: 3/4" diameter with a 10" overall length for versatile use in medium to larger workpieces and through-hole machining.
• MT7 Shank: Precision Morse taper interface for secure, stable mounting in compatible milling machines.
• Thread Form Compatibility: Engineered to reliably form UN, UNC, UNF, UNEF, and UNS threads, offering flexibility across common engineering standards.

This thread mill excels in production and precision environments where clean, accurate threaded holes are essential. The through-coolant feature helps maintain steady chip clearance, minimizes dwell time, and reduces tool wear, contributing to more consistent hole quality and lower tooling costs per part. Ideal for automotive, aerospace, mold making, and general engineering applications where durable, reliable threading is required.
