The Carmex MTZ through-coolant thread mill is a precision carbide tool engineered for reliable metric threading in through-holes. Designed for demanding production environments, it delivers coolant directly to the cutting edge for consistent, clean threads and efficient chip evacuation.

• Through-Coolant Flute Design: Coolant is delivered along the flutes to the cutting edge, optimizing heat management and helping maintain dimensional accuracy during threading.
• Carbide Construction: High-hardness carbide body provides exceptional wear resistance for long-lasting performance on demanding materials.
• Metric Thread Size: M12 x 1.75 threading specification for standard, precise metric fastener compatibility.
• MT7 Shank: MT7 taper ensures rigid, repeatable tool seating and minimizes runout in compatible tool holders.
• Through-Hole Thread Milling: Flute geometry and cutting edge design are optimized for threading through holes with direct chip removal for smooth operation.
• Compatibility with Minimal-Coolant Setups: Effective in machines without external coolant systems by using through-flute coolant delivery to the cutting zone.

The MTZ family from Carmex is built for precision threading and superior performance across a range of industrial applications. Use cases include production runs that require rapid, accurate M12 x 1.75 threads in through-holes, aerospace fastener inserts, automotive components, and general engineering projects. With direct coolant delivery and a robust MT7 shank, this thread mill helps reduce cycle times, improve surface finish, and extend tool life, making it a reliable choice for shops seeking consistent results and streamlined tooling setups.
