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.

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.

Medium inserts remove a moderate amount of material for a semi-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.

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.
