Carmex MTB solid carbide thread mills deliver precise NPT threading with the reliability you expect from a high‑performance carbide tool. Built for CNC applications, this MT7‑shank mill integrates cutting‑edge through‑coolant technology to keep chips moving and temperatures down, even in deep or hard‑to‑reach bores.

• Through-Coolant Bore: Delivers coolant directly through the tool to the cutting edges for superior cooling and effortless chip evacuation in deep holes.
• Solid Carbide Construction: Combines exceptional hardness and wear resistance with rigidity for repeatable, accurate thread milling in demanding materials.
• MT7 Shank: Provides a robust, high‑rigidity connection to compatible CNC holders for improved stability and tolerance control.
• NPT Thread Milling Range: Optimized for 1/4" to 3/8" nominal NPT threads with 18 TPI, enabling clean, consistent threads in a single operation.
• MTB Line Advantage: A refined thread milling platform that emphasizes cooling efficiency and tool longevity without compromising precision.

The through‑coolant capability reduces heat buildup and helps maintain thread geometry over longer cutting cycles, which translates to fewer tool changes and more consistent thread quality. By enhancing chip clearance and cooling at the point of cut, these mills deliver reliable production performance for parts requiring precise NPT threads—from aerospace housings to hydraulic components—while preserving tool life and reducing overall costs.
