Carbide Inserts for Multiple Materials
Choose these premium turning carbide inserts to cut a variety of materials without changing out your tool. For optimized performance, choose a premium insert designed for your workpiece material. These inserts are made of superior carbide for longer life and a smoother finish on your workpiece than economy inserts. Install inserts into a matching holder.
Inserts with a larger nose angle and tip radius remove more material with each pass but cut less precisely than smaller inserts. Select the insert with the largest nose angle and tip radius that will turn your workpiece to the desired shape.
Positive-rake inserts stick out in front of the holder to reach tight spaces on the workpiece. However, they only have cutting edges on one side.
Use finishing inserts at the end of your turning process to remove minimal material for a smooth surface finish.
Inserts for semi-interrupted cutting conditions are the most commonly used, often to machine imperfectly round workpieces, such as shafts with a keyway.

Economy Carbide Inserts
Install these carbide inserts into a matching holder. 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.
Coated inserts last longer and can be run at faster speeds than uncoated inserts.

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.
