Carmex Thread Mills Carbide - Through Coolant (Flutes) - Metric - M10, M12 x 1.5 - MT7

The Carmex MTZ Through-Coolant Carbide Thread Mills are precision tools designed for reliable threading in through-holes. Built for metric M10 and M12 x 1.5 threads with an MT7 shank, they deliver coolant directly to the cutting edge for smoother, more efficient thread milling.

• Tool design: Through-coolant channel delivers coolant directly to the cutting edge, reducing heat and improving chip control.
• Shank & sizes: MT7 shank compatibility with metric thread milling options M10 and M12 x 1.5.
• Material & coating: Solid carbide construction for high rigidity and wear resistance in demanding materials.
• Chip evacuation: Optimized flute geometry supports direct chip removal for cleaner cuts and fewer interruptions.
• Application: Especially effective for threading through holes where through-hole coolant enhances reliability and finish.
• Machining compatibility: Suitable for machines without external coolant systems thanks to integrated through-coolant delivery.

With coolant routed through the flutes, these mills maintain cutting-edge temperatures, improving thread form accuracy and surface finish while extending tool life. The direct-chip evacuation minimizes buildup and dwell time, enabling deeper threads and more consistent results across runs. The MT7 shank broadens compatibility with a wide range of CNC setups, making these mills a dependable choice for production environments that demand precise, repeatable threaded features in automotive, aerospace, and general engineering applications.
