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.
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. 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.
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.

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.
S-code holders secure inserts with a screw for easy indexing. They’re the most commonly used holders with positive-rake inserts.

Boring Carbide Insert Holders
These holders conform to ANSI standards. Pair them with an ANSI standard carbide insert (sold separately) to enlarge existing holes to precise diameters. When one edge of the insert dulls, just rotate it to use another edge. Right-hand holders are for boring when the workpiece is rotating counterclockwise (toward the lathe operator). Left-hand holders are for boring when the workpiece is rotating clockwise (away from the lathe operator).
