Cut aluminum, copper, brass, and other non-ferrous materials with these premium inserts. Their chipbreakers are designed for turning soft, sticky metal—they break and curl chips before they become long enough to cause damage. Install these inserts in 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.

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.

Positive-rake inserts stick out in front of the holder to reach tight spaces on the workpiece. They only have cutting edges on one side, so they don’t last as long as negative-rake inserts. Medium inserts remove a moderate amount of material for a semi-smooth surface finish.

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.
