The Carmex MTB Solid Carbide Thread Mills with Through Coolant are engineered for shops that demand repeatable, precise internal threads in metal parts. Designed for high-speed milling centers and CNC machines, this MT7-equipped tool delivers reliable performance in demanding threading tasks.

• Through‑coolant bore: Delivers coolant directly to the cutting edge and bore area, enhancing chip evacuation and cooling for cleaner threads and longer tool life.
• Solid carbide construction: Unmatched hardness and wear resistance for consistent thread accuracy across tough materials.
• MT7 shank: Robust Morse taper connection for rigid, vibration‑free performance in demanding machining environments.
• Thread form: NPSF thread milling profile optimized for clean, accurate internal threads in holes of varying depth.
• Size and pitch: Cutting diameter range 1/2" to 3/4" with a 14 TPI thread pitch, catering to common precision applications with a single, versatile tool.
• Deep-hole threading capability: Through-bore coolant supports longer hole depths and more consistent chip control during extended cycles.

This MTB thread mill is ideal for production runs requiring dependable internal threads, such as automotive, hydraulic, and general precision metalworking. The integrated cooling through the bore helps prevent heat build-up, reduces chip recutting, and contributes to steadier tolerances. By combining durable carbide with a through-coolant design, it offers improved longevity and cost efficiency without compromising thread quality or surface finish. Whether you’re threading through holes or reaching deep cavities, this tool is built to maintain performance across demanding machining campaigns.
