Carmex MTB Thread Mills are a solid carbide solution crafted for precise internal threading with through‑coolant. Designed for machinists and engineers who need dependable NPSF threads in challenging materials, these MT7‑shank tools deliver clean form and extended tool life.

• Through-Coolant Bore: Coolant flows through the tool bore to wash chips from the threaded hole and cool the cutting edge, improving chip control and reducing heat buildup.
• Solid Carbide Construction: High‑rigidity substrate delivers accurate thread profiles and long wear resistance for demanding production runs.
• MT7 Morse Taper Shank: Secure, precise fit for compatible spindles, enabling consistent performance and easy tool changes in CNC machines.
• Internal Thread Capability: Specifically designed for 1/8 x 27 NPSF threads, enabling reliable, repeatable thread formation in tight spaces.
• MTB Line Innovation: Built on Carmex’s MT lineage and enhanced with through‑bore cooling, delivering improved durability and process stability.
• Versatile Application: Ideal for precision components and assemblies where internal threads must be machined cleanly in harder materials.

The through‑coolant design targets two key benefits: efficient chip evacuation from the threaded hole and extended tool life through better thermal management. This means fewer tool changes, more consistent thread quality, and predictable performance across production runs. Suitable for a range of precision machining environments, Carmex MTB thread mills help you achieve reliable, repeatable internal threading without compromise.
