Alumina Ceramic Inserts
These inserts are made with a black alumina ceramic on the cutting edges. Compared to carbide inserts, ceramic lasts longer in hardened-steel tooling applications because it is chemically inert and has better heat resistance. Ceramic inserts have comparable wear resistance to cubic boron nitride, but ceramic is best for continuous and light cutting while cubic boron nitride can also be used in heavy interruption. These inserts have multiple cutting edges, so when a cutting edge becomes dull, rotate the insert in the holder to use a sharp edge. Larger nose angles and larger tip radii provide a stronger cutting edge but result in increased vibration and a rougher finish.
Positive-rake inserts have an edge that is less than 90° to sit flat in the holder for improved cutting clearance and a better finish than negative-rake inserts. They have cutting edges on one side of the inserts.
Negative-rake inserts have a 90° edge and sit at an angle in the holder to provide a strong cutting force for heavy duty applications. They have cutting edges on both sides of the inserts for twice the life of comparable positive-rake inserts.

SiAlON Ceramic Inserts
These inserts are made with SiAlON on the cutting edges. SiAlON is a ceramic made from silicon, aluminum, oxygen, and nitrogen that has a balance of wear resistance, chemical resistance, toughness, and heat resistance that makes it good for roughing applications of heat-resistant alloys such as 625 and 718 nickel. Select the medium grade for semi-finishing, milling, and continuous or light interruption applications. Select the roughing grade for higher interruption applications. These inserts have multiple cutting edges, so when an edge becomes dull, rotate the insert in the holder to use a sharp edge. Larger nose angles and larger tip radii provide a stronger cutting edge but result in increased vibration and a rougher finish.
Positive-rake inserts have an edge that is less than 90° to sit flat in the holder for improved cutting clearance and a better finish than negative-rake inserts. They have cutting edges on one side.
Negative-rake inserts have a 90° edge and sit at an angle in the holder to provide a strong cutting force for heavy duty applications. They have cutting edges on both sides for twice the life of comparable positive-rake inserts.
