The Carmex MTZ Thread Mills in Carbide are precision tools designed for through-hole threading, delivering coolant directly to the cutting edge for cleaner, cooler, and more reliable threads. Ideal for shops that need high-precision internal threads on machines without external coolant systems.

• Through-Coolant Delivery: coolant travels through the flute to the cutting edge, enhancing heat removal and chip control for consistent thread quality.
• Thread Milling for Through Holes: optimized flute geometry and cutting edges tailored for threading inside through holes with efficient direct chip evacuation.
• Thread Forms Supported: compatible with UN, UNC, UNF, UNEF, and UNS thread standards to cover a wide range of applications.
• Carbide Construction: rigid carbide body provides high dimensional stability, wear resistance, and prolonged tool life under demanding milling conditions.
• MT7 Shank: MT7 tooling interface fits a broad selection of CNC mills and machining centers, enabling versatile deployment.
• Size: 1 - 1 1/2 x 12 (as specified by the product title), detailing the cutting diameter range and corresponding length for reliable threading performance.

In practice, this MTZ thread mill reduces cycle times and improves thread accuracy by maintaining a cooler cutting zone and ensuring smooth chip evacuation. The through-flute coolant design makes internal threading feasible on equipment without external coolant lines, broadening where you can achieve precise UNC/UNF/UNEF/UNS threads. Choose this tool when you need dependable, repeatable internal threads in metal parts such as housings, blocks, and assemblies, with a focus on cleaner finishes and extended tool life.
