Heat resistant and wear resistant, these inserts cut super alloys—such as Inconel and Waspaloy—and titanium better than premium general use 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.

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.

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.

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.
