Introducing Carmex MTB solid carbide thread mills with through coolant, engineered for precise NPTF internal threads on 1/2"–3/4" diameters (14 TPI). The MT7 shank delivers rigid, repeatable performance in demanding production environments.

• Thread Form and Size: NPTF threads for 1/2"–3/4" major diameter with 14 threads per inch (14 TPI).
• Through-Coolant Bore: Coolant is delivered through the tool bore to the cutting edge, enhancing chip removal and reducing cutting temperatures.
• Solid Carbide Construction: High-hardness carbide core provides rigidity, wear resistance, and extended tool life under demanding cutting conditions.
• MT7 Shank: MT7 taper ensures secure, stable seating in compatible milling centers for accurate threading results.
• Applications: Ideal for hydraulic and pneumatic components, manifolds, and precision fixtures that require reliable internal NPTF threads with consistent tolerances.

Through-coolant capability and the rugged carbides work together to keep chips moving and heat under control, delivering cleaner threads, steadier tolerances, and longer tool life. The MTB design focus supports longer production runs with fewer tool changes, making this tool a dependable choice for high-demand threading tasks. Whether you’re threading hydraulic blocks or automotive fixtures, this mill provides repeatable performance, helps minimize rework, and supports efficient, cost-conscious manufacturing.
