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.
Negative-rake inserts are the first choice for most turning applications. With strong cutting edges on two faces, they last longer than comparable positive-rake inserts. When all the edges on one face are worn, flip the insert over.
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. Inserts for interrupted cutting conditions are best for workpieces that will come in and out of contact with the insert, such as hexagonal bars.

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.
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.
Coated inserts last longer and can be run at faster speeds than uncoated inserts.

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

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.

Turning Carbide Insert Holders

Secure carbide inserts inside these holders for stable turning. They’re also known as indexable insert holders. Select a holder that’s compatible with your insert by matching the insert style and inscribed circle diameter (IC). Right-hand holders move from right to left toward the lathe chuck, left-hand holders move from left to right away from the lathe chuck, and neutral holders can cut in either direction.
M-code holders secure inserts with both a top clamp and a pin lock, so they’re often used for interrupted or semi-interrupted cuts to keep inserts stable despite vibration. They’re the most commonly used holders with negative-rake inserts.
D-code holders require just a quick motion to remove inserts from their wedge clamp. However, they hold inserts less securely than M-code holders.
Holders with an offset shank are good for reaching into tight corners and when working close to the chuck.

Cubic Boron Nitride Inserts
Resisting wear and fractures when cutting hardened steel, these cubic boron nitride inserts last longer than carbide inserts. Use them for high-speed finishing and interrupted cutting applications. All have multiple cutting edges, so when an edge dulls, rotate the insert in your holder to use a sharp edge. Those with larger nose angles and tip radii have stronger cutting edges, but create more vibration and a rougher finish.
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.
