    Economy Lathe Tool 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.

    Individual—Inserts sold individually come packed in a clear plastic case to protect cutting edges during shipment.
    Package—Inserts sold in packages come factory sealed from the manufacturer for maximum traceability.
    Titanium Nitride (TiN) Coated—Coated inserts last longer and can be run at faster speeds than uncoated inserts.
    Positive Rake Angle—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.

    Lathe Tool Inserts for Multiple Materials

    Choose these premium carbide inserts to turn a variety of materials without changing out your tool. They’re made of higher-quality carbide than economy inserts, so they last longer and create a smoother finish. Install them into a matching holder. For the best performance, choose an insert designed for the material of your workpiece.
    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.

    Clear Plastic Case

    Inserts without chipbreakers are best for making shallow cuts or for finishing surfaces.
    For Semi-Interrupted Cutting Conditions—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.
    Individual—Inserts sold individually come packed in a clear plastic case to protect cutting edges during shipment.
    Package—Inserts sold in packages come factory sealed from the manufacturer for maximum traceability.
    Uncoated—Uncoated inserts are sharper than coated inserts, so they leave a better finish on softer metals, such as aluminum. They’re good for general purpose cutting and short production runs.
    Positive Rake Angle—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.
    For Finishing Cutting Operation—Use finishing inserts at the end of your turning process to remove minimal material for a smooth surface finish.

    Turning Lathe Tool Insert Holders

    Image of Product. Front orientation. Lathe Tool Insert Holders. Turning Lathe Tool 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.

    Cermet Lathe Tool Inserts for Steel

    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.
