Features and Benefits
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
Oxide prevents chip building, galling and welding on the workpiece. It is commonly used on low carbons, stainless steel and iron based ferrous metals.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
Spiral flute reamers are used in blind and through-hole operations. They are used to bridge interrupted cuts.
