Features and Benefits
Solid carbide provides better rigidity than high speed steel. It is extremely heat resistant and used for high speed applications on cast iron, nonferrous materials, plastics and other tough-to-machine materials.
Aluminum chromium nitride (AlCrN) has a higher heat resistance than AlTiN. It is commonly used for machining aircraft and aerospace material, nickel alloy, stainless steel, titanium, cast iron and carbon steel.
Center Cutting tools have one or more cutting edges at the tip and are used in a variety of applications including plunging, drilling or ramping.
