Designed for precision threading in through-hole applications, Carmex MTZ carbide thread mills deliver coolant directly through the flutes to the cutting edge. This 1/2" diameter, 20 TPI tool is ideal for standard inch thread forms (UNC, UNF, UNEF, UNS) and helps achieve smooth, reliable threads with every pass.

• Through-flute coolant delivery: Coolant is directed through the flutes to the cutting edge for improved heat control and chip evacuation, enabling stable threading.
• Threading focus for through holes: Optimized for threading through holes with direct chip removal, boosting efficiency and surface finish.
• Size and thread compatibility: 1/2" diameter with 20 TPI, supporting UNC, UNF, UNEF and UNS thread standards.
• Carbide grade: MT7 solid carbide delivers excellent wear resistance and toughness for demanding machining environments.
• MTZ family design: Part of Carmex’s MTZ range, specifically engineered to maximize internal cooling through the flutes.
• Machine compatibility: Designed to perform on machines without external coolant systems, expanding where you can thread mill with confidence.

This combination of through-coolant delivery, through-hole threading optimization, and durable MT7 carbide makes the Carmex MTZ 1/2 x 20 MT7 thread mill a practical choice for automotive, aerospace, and general manufacturing gear where precise, high-quality threads are essential. The tool’s internal coolant through the flutes helps maintain consistent thread quality, reduces heat-related distortion, and supports longer tool life in repetitive production scenarios.
