The Carmex MTZ carbide thread mill with through-coolant is engineered for precision internal threading in through-holes. Part of the MTZ family, it delivers coolant through the flutes to the cutting edge for smooth cuts and reliable chip evacuation, even in demanding materials, with an MT7 shank for broad machine compatibility.

• Thread size and standards: 1/4-28 with support for UNC, UNF, UNEF, and UNS thread forms
• Shank compatibility: MT7 shank fits a wide range of milling centers and toolholders
• Through-coolant design: coolant flows through the flutes directly to the cutting edge for improved cooling and lubrication
• Material: solid carbide for rigidity, wear resistance, and precise threading
• Chip evacuation: optimized for direct chip removal in through-hole threading, reducing clogging and downtime
• Machine compatibility: performs well on systems without external coolant supply
• Application: ideal for internal threading in through-holes across a variety of materials

With through-flute coolant delivering cooling right at the cutting edge, this thread mill maintains stable temperatures, preserves thread form, and enhances surface finish on internal threads. The direct chip removal design minimizes interruptions in production, while the carbide construction and MT7 shank deliver dependable performance for everyday manufacturing and precision work alike.
