Carmex MT Thread Mills deliver precise internal and external threading in a solid carbide tool designed for CNC mills. Built for shops that demand reliable, cost‑effective NPT threads, these mills combine robust rigidity with efficient cutting performance.

• Material: Solid carbide construction provides exceptional rigidity and wear resistance for demanding threading tasks.
• Threading capability: Cuts both internal and external threads, including NPT profiles, in a single setup.
• Flute count: Optimized with 3–5 flutes to balance strength, chip evacuation, and thread form quality.
• Size and compatibility: 2.5 in diameter with MT7 shank for compatibility with standard CNC spindles and toolholders.
• Design efficiency: Specialized flute geometry reduces cutting forces and improves thread quality and cycle efficiency.

This tool enables accurate NPT threading in a range of metals without swapping between taps or separate tooling. The MT7 shank integrates smoothly with common CNC setups, helping minimize downtime from tool changes. With a multi‑flute design and carbide construction, you’ll achieve clean thread forms, better surface finish, and longer tool life on production runs. Ideal for manufacturing valve bodies, hydraulic fittings, piping adapters, and other components that require dependable NPT threads.
