Features and Benefits
NPT (National Pipe Taper) refers to American National Standard Taper Pipe Threads. They are commonly used for general purpose applications and require a sealant.
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
Hardlube is a multi-layered coating composed of titanium aluminum nitride and tungsten carbide/carbon (TiAIN/WC/C). It is stronger and more wear resistant than TIAlN. It is commonly used on steel, stainless steel, nickel and cobalt.
Modified bottoming chamfers are similar to bottoming chamfers, but they are longer and have more teeth. They are used for threading to the bottom of blind holes and have 2 to 2-1/2 threads.
