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.

Optimized for use on steel, these inserts can run at higher cutting speeds and will last longer than inserts for multiple materials. 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.

After choosing nose angle and rake type, consider roughing inserts for removing material quickly when surface finish isn’t a concern. Medium inserts remove a moderate amount of material for a semi-smooth surface finish. 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.

Heat resistant and shaped for turning stainless steel specifically, they’ll last longer than inserts for multiple materials. Install inserts into a matching holder.

Choose inserts for continuous cutting conditions when machining pieces that allow for constant contact between the insert and the workpiece, such as round rods. Inserts for semi-interrupted cutting conditions are the most commonly used, often to machine imperfectly round workpieces, such as shafts with a keyway. Inserts for interrupted cutting conditions are best for workpieces that will come in and out of contact with the insert, such as hexagonal bars.
