Turnkey solution for precision metric threading. The Carmex MTZ Through-Coolant Thread Mills are carbide tools engineered for threading through-holes on M16x2, M18x2, and M20x2, with an MT7 shank for broad machine compatibility.

• Through-coolant flute design: Channels built into the flutes deliver coolant directly to the cutting edge, enabling efficient heat removal and superior surface finish.
• Carbide construction: Hard, wear-resistant substrate for reliable performance in demanding threading applications and extended tool life.
• Metric thread range: Optimized for precise threading of M16x2, M18x2, and M20x2 through-holes, reducing setup time and increasing first-pass accuracy.
• MT7 shank: Robust, widely compatible shank size that fits a broad range of standard MT7 tool holders for flexible integration on existing rigs.
• Direct chip removal: Designed to evacuate chips efficiently from through-holes, minimizing clogging and maintaining consistent thread quality.
• Machining versatility: Ideal for facilities without external coolant systems, as the integrated through-flute cooling supports reliable operation across machines with varied coolant capabilities.

This MTZ tool geometry is purpose-built for threading through holes with consistent, repeatable results. By combining through-coolant delivery, carbide durability, and a versatile MT7 shank, it supports higher cutting speeds, cleaner thread profiles, and longer tool life—benefiting automotive, hydraulic, and general mechanical manufacturing environments where precision threading matters.
