Carmex MTZ Through Coolant Carbide Thread Mill is built for precise, efficient threading in through-hole applications. This 1/8"-27 NPT tool with an MT7 shank delivers coolant directly to the cutting edge for cleaner cuts and longer tool life, making it a reliable choice for shops that demand consistent thread quality.

• Through-Coolant Flutes: Coolant is guided through the flute channels to the cutting edge, improving lubrication, heat control, and chip evacuation.
• 1/8"-27 NPT Thread Milling: Specifically designed to produce 1/8" diameter, 27 TPI NPT threads in through holes in a single setup.
• Carbide Construction: Premium carbide build provides wear resistance and stable performance at higher cutting speeds.
• MT7 Shank: Morse Taper 7 shank for solid retention and rigid alignment in compatible machine spindles.
• Direct Chip Removal: Flute geometry supports immediate chip evacuation from through holes, reducing clogging and re-cutting.
• Optimized Flute Geometry: Engineered flute profile and helix angle deliver smooth cutting action and consistent thread form.

This tool’s through-coolant design reduces heat buildup at the cutting edge, enabling deeper, more reliable threads with tighter tolerances. The ability to deliver coolant directly to the workpiece edge supports cleaner finishes and longer tool life, while the through-hole threading setup minimizes secondary operations. Designed for versatile use, it performs well on machines without external coolant connections, helping streamline setups and improve overall machining efficiency.
