The Carmex MTZ carbide thread mill with through-coolant is a precision tool designed for through-hole NPT threading. Built for shops and manufacturers that demand clean, accurate threads with efficient chip evacuation, it excels in challenging through-hole applications while simplifying coolant delivery.

• Tool family: MTZ carbide thread mill with through-flute cooling for direct coolant delivery to the cutting edge.
• Shank type: MT7 Morse taper shank, compatible with a wide range of milling machines for quick tool changes.
• Threading capability: NPT threads in through-holes, sized from 1/4" to 3/8" with 19 TPI.
• Coolant delivery: Through-flute design channels coolant directly to the cutting edge, enhancing cooling and flushing of chips.
• Material: Solid carbide construction for high rigidity, heat resistance, and long tool life.
• Chip removal: Direct chip exit through the hole simplifies machining and reduces heat buildup at the tip.
• Surface finish: Designed to produce consistent, tight-thread profiles with improved surface quality on through-hole engagements.

This tool is ideal for production environments that require reliable NPT threading in through-holes, where traditional external coolant setups are limited or unavailable. The through-coolant capability minimizes thermal distortion and wear, enabling higher cutting speeds and longer interval tooling. Whether you’re threading hydraulic components, fittings, or pipe assemblies, this MTZ thread mill delivers stable performance, reduced rework, and straightforward setup—no need for external coolant plumbing on compatible machines.
