The Carmex MTZ Through-Coolant Carbide Thread Mills are engineered for precise threading in through-holes, delivering coolant directly through the tool’s flutes to the cutting edge for smoother, more efficient cuts. Designed to handle UNC, UNF, UNEF, and UNS threads, this MT7 shank tool is built for reliability in demanding metalworking environments.

• Through-Coolant Flute Design: Delivers coolant directly to the cutting edge through the flutes, helping control heat and improve chip evacuation during thread milling.
• Carbide Construction: Hard, wear-resistant carbide provides extended tool life and consistent performance at higher cutting speeds.
• MT7 Shank: Robust, rigid interface compatible with a wide range of CNC milling centers for stable, precise threading.
• Thread Form Compatibility: Optimized for UN-standard threads—UNC, UNF, UNEF, and UNS—with a 5/16 x 18 size for common through-hole applications.
• Through-Hole Threading: Specifically designed to thread through holes with direct chip removal, reducing downtime and simplifying setups.
• Direct Chip Removal: Flute geometry supports efficient chip flow away from the cutting edge, aiding surface finish and thread integrity.

Benefits: By integrating coolant delivery through the flutes, this thread mill maintains stable temperatures at the cutting edge, which enhances thread accuracy and surface finish while extending tool life. The through-coolant design eliminates the need for external coolant lines in many setups, making it well-suited for machines without dedicated coolant plumbing. Ideal for through-hole threading in steel, stainless steel, and other metals, the MTZ thread mill supports higher productivity with reliable, repeatable threads and reduced downtime. This makes it a practical choice for shops focused on precision aerospace, automotive, and general manufacturing applications where consistent thread quality matters.
