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.
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.

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.
