Meet the Carmex MTZ Through-Coolant Thread Mill — a carbide tool engineered for precise internal threading in through-holes. Designed for shops that run threading on machines without external coolant, it delivers coolant directly to the cutting edge for clean, consistent threads.

• Thread size: Metric M12 x 1.75 threading with a robust MT7 shank for dependable engagement in CNC spindles.
• Through-coolant design: Coolant is delivered through the flutes to the cutting edge, enhancing cooling and chip control during deep-threading passes.
• Flute geometry: Flutes are engineered for direct chip removal from through-holes, helping maintain stable cutting conditions and surface finish.
• Material: Solid carbide construction delivers stiffness, wear resistance, and long tool life in demanding threading applications.
• Application focus: Optimized for threading through-holes across common metals, with reliable performance even when external coolant isn’t available.

This MTZ thread mill offers real-world benefits: precise thread forms with consistent pitch, reduced heat buildup at the cutting edge, and smoother finishes on threaded profiles. The through-coolant channel minimizes chip recutting and can shorten cycle times, making it a practical choice for high-volume or precision threading tasks where coolant access is limited.
