Carmex MTB Solid Carbide Through-Coolant Thread Mills are precision tools designed for reliable UNC/UNF/UNEF/UNS thread milling on CNC mills. Built for engineers and machinists who demand consistent thread quality, these mills pair carbide rigidity with coolant-through capability to keep holes clear and tools lasting longer.

• Through-Coolant Bore: Delivers coolant directly through the tool to the cutting edge, improving chip evacuation and reducing thermal buildup for steadier threading.
• Solid Carbide Construction: Offers high stiffness and wear resistance for repeatable, accurate thread profiles across demanding materials.
• Size and Thread Compatibility: 1/2" cutting diameter with 13 TPI (1/2 x 13) compatible with UNC, UNF, UNEF, and UNS thread forms.
• MT7 Shank: Morse Taper 7 shank for secure seating and rigid performance in MT7-compatible holders and machines.
• MTB Through-Coolant Innovation: Builds on Carmex MT line with integrated bore cooling to extend tool life and enhance process reliability.
• Versatile Thread Milling: Suitable for both internal and external threading applications across a range of production environments.

With coolant flowing through the bore, this tool minimizes chip buildup, preserves threading accuracy, and enables deeper, cleaner threads. The robust carbide body enhances rigidity and wear resistance, while the MT7 interface ensures dependable alignment and stability on compatible machines. This combination delivers consistent thread quality, reduced downtime, and cost efficiency in automotive, aerospace, and general manufacturing settings where standard UNC/UNF/UNEF/UNS threads are required.
