Features and Benefits
Modified bottoming is similar to bottoming, but the chamfer is longer and has more teeth. They are used for threading blind holes and have 2 to 2-1/2 threads.
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
Nitride/Oxide is used to prevent galling, welding and loading. It is commonly used on low carbon steels, stainless steels and nonferrous metals.
