The Carmex Thread Mills Carbide Through-Coolant (Flutes) for NPTF threading combines precision threading with efficient chip control, designed for through-hole applications. With a 1/8 x 27 size and MT7 shank, it’s built for reliability in a wide range of CNC setups, including machines without external coolant.

• Through-Coolant Flute Design: coolant is delivered through the flutes directly to the cutting edge, enhancing cooling, reducing chip crowding, and improving surface finish.
• Carbide Construction: high-hardness carbide provides wear resistance and long tool life for demanding threading tasks.
• NPTF Thread Form: optimized for precise National Pipe Tittings Forum threads, delivering consistent pitch and accuracy in through-hole machining.
• 1/8 x 27 Size: compact, versatile thread mill ideal for small-diameter internal threads common in pneumatic, hydraulic, and fittings work.
• MT7 Morse Taper Shank: compatible with a broad family of preloaded MT7 spindles for stable, chatter-free performance.
• Direct Chip Evacuation for Through Holes: flute geometry supports efficient chip removal when threading through-thru features, reducing rework risk.
• Works with Minimal Coolant Infrastructure: designed to perform well even on machines without an external coolant line, thanks to its integrated through-coolant delivery.

This thread mill is ideal for shops performing internal pipe-thread work, manifolds, and components requiring precise NPTF threads in through-holes. The through-coolant capability helps maintain a clean cutting zone, extend insert life, and sustain consistent thread quality across production runs. Its robust carbide composition and MT7 shank deliver dependable performance in a variety of materials and spindle setups, making it a practical choice for precision threading without the need for complex cooling arrangements.
