Combine the strength and wear resistance of high-performance metals with the heat resistance of ceramic—these cermet inserts cut steel at higher speeds and last longer than standard carbide inserts. Their PVD coating keeps them sharper longer than CVD-coated inserts. This means you can also use them as precision inserts or to cut non-ferrous metals. Install them in a matching holder.

Inserts with a larger nose angle and tip radius remove more material with each pass, but they cut less precisely than smaller inserts. Select the insert with the largest nose angle and tip radius that will turn your workpiece to the shape you want.

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. However, they only have cutting edges on one side.

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.
