Description
Meet the Carmex MTZ Thread Mills Carbide with Through Coolant. Designed for threading through holes, this tool delivers coolant directly to the cutting edge for smooth, precise NPTF threads—even on machines without an external coolant system.
- Through-coolant flute design: Coolant is delivered through the flutes to the cutting edge, improving lubrication, heat management, and chip control for a cleaner cut.
- NPTF threading capability: Specifically engineered for National Pipe TTF threading on through-holes, with a 1/4"–3/8" diameter range and 18 TPI.
- Carbide construction: Premium carbide core offers exceptional hardness and wear resistance for enduring accuracy in challenging materials.
- MT7 shank: Rigid MT7 shank provides a secure, stable fit in common CNC tool holders for accurate, repeatable threading.
- Direct chip removal: Flute geometry enables efficient debris evacuation in through-hole work, reducing re-cutting and cycle interruptions.
- Compatibility with coolant-less setups: Optimized to perform effectively even when an external coolant supply isn’t available, expanding machining versatility.
The MTZ carbide thread mill delivers consistent, high-quality NPTF threads with improved surface finish and longer tool life thanks to targeted cooling and efficient chip removal. Ideal for pipe fittings, hydraulic components, and other through-hole applications, this tool helps you achieve precise threads, faster cycles, and reliable assembly without the need for complex coolant infrastructure.
