Our NPTF Thread Mills are engineered for precision, performance, and leak-free dry seal pipe threading. Designed to meet National Pipe Taper Fuel (NPTF) standards, these tools ensure tight, high-pressure connections without the need for sealants. Manufactured from premium submicron grade carbide, they deliver exceptional strength, wear resistance, and consistency. Available in straight, staggered, or helical flute designs—with optional AlTiN+ coating for extended tool life and higher cutting speeds—our NPTF thread mills offer clean, accurate internal threads with excellent chip control. Ideal for critical applications in hydraulic, pneumatic, and fuel systems.
