Carbide Inserts for Multiple Materials
Choose these premium carbide inserts to turn a variety of materials without changing out your tool. They’re made of higher-quality carbide than economy inserts, so they last longer and create a smoother finish. Install them into a matching holder. For the best performance, choose an insert designed for the material of your workpiece.
Inserts with a larger nose angle and tip radius remove more material with each pass, but they cut less precisely than smaller inserts. Select the insert with the largest nose angle and tip radius that will turn your workpiece to the shape you want.
Inserts for semi-interrupted cutting conditions are used to machine imperfectly round workpieces, such as shafts with a keyway. They’re the most common type of insert.
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. Use finishing inserts at the end of your turning process to remove minimal material for a smooth surface finish.
Inserts with a titanium aluminum nitride (TiAlN) coating dissipate heat well, especially at high speeds. The coating reacts to high temperatures by forming a layer of aluminum oxide. This layer transfers heat to the chips, so the tool stays cool even without lubrication.
Inserts with chip breakers prevent long chips from forming, so they won’t block the flow of coolant or damage your tool.
Inserts sold in packs come factory sealed from the manufacturer for maximum traceability. Inserts sold individually come packed in a clear plastic case to protect cutting edges during shipment.

Carbide Inserts for Steel
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.
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 sold individually come packed in a clear plastic case to protect cutting edges during shipment. Inserts sold in packs come factory sealed from the manufacturer for maximum traceability.

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.
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.
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 sold individually come packed in a clear plastic case to protect cutting edges during shipment. Inserts sold in packs come factory sealed from the manufacturer for maximum traceability.

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.
Holders with an offset shank are good for reaching into tight corners and when working close to the chuck.
