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

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.

Titanium Aluminum Nitride (TiAlN) Coated—Inserts with a titanium aluminum nitride (TiAlN) coating dissipate heat well, especially at high speeds. The coating reacts to high temperatures by forming a layer of aluminum oxide. This layer transfers heat to the chips, so the tool stays cool even without lubrication.

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 Medium Cutting Operation—Medium inserts remove a moderate amount of material for a semi-smooth surface finish.

Chip Breakers—Inserts with chip breakers prevent long chips from forming, so they won’t block the flow of coolant or damage your tool.

Clear Plastic Case

For Interrupted Cutting Conditions—Inserts for interrupted cutting conditions are best for workpieces that will come in and out of contact with the insert, such as hex bars.

Individual—Inserts sold individually come packed in a clear plastic case to protect cutting edges during shipment.

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.

Titanium Nitride (TiN) Coated—Titanium nitride (TiN) coated inserts create less friction than uncoated inserts, so they last longer when run at similar speeds.

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 Roughing Cutting Operation—Roughing inserts are used for removing material quickly when surface finish isn’t a concern.

For Medium Cutting Operation—Medium inserts remove a moderate amount of material for a semi-smooth surface finish.

For Finishing Cutting Operation—Use finishing inserts at the end of your turning process to remove minimal material for a smooth surface finish.

Chip Breakers—Inserts with chip breakers prevent long chips from forming, so they won’t block the flow of coolant or damage your tool.

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.

Lathe Tool Inserts for Steel

Optimized for use on steel, these inserts can run at higher cutting speeds and will 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.

Clear Plastic Case

For Semi-Interrupted Cutting Conditions—Inserts for semi-interrupted cutting conditions are the most commonly used, often to machine imperfectly round workpieces, such as shafts with a keyway.

Individual—Inserts sold individually come packed in a clear plastic case to protect cutting edges during shipment.

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 Medium Cutting Operation—Medium inserts remove a moderate amount of material for a semi-smooth surface finish.

Clear Plastic Case

For Semi-Interrupted Cutting Conditions—Inserts for semi-interrupted cutting conditions are the most commonly used, often to machine imperfectly round workpieces, such as shafts with a keyway.

Individual—Inserts sold individually come packed in a clear plastic case to protect cutting edges during shipment.

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 Roughing Cutting Operation—Roughing inserts are used for removing material quickly when surface finish isn’t a concern.

For Medium Cutting Operation—Medium inserts remove a moderate amount of material for a semi-smooth surface finish.

For Finishing Cutting Operation—Use finishing inserts at the end of your turning process to remove minimal material for a smooth surface finish.

Counterbore Insert Holders

Shown with Inserts (Sold

Separately)

Designed to reduce waste and costs during high-volume jobs, these counterbores consist of both an insert and a holder. When the cutting edges dull, you can replace the insert rather than the entire tool. The inserts are locked in place with a screw for a hold that’s strong enough to handle the high speeds of a CNC machine. These counterbores create flat-bottomed holes that allow socket head screws to sit flush with the surface of your material.

Carbide Inserts


Individual Carbide Insert Case

Inserts have a positive rake, which means the cutting edge is angled to reduce vibration and prevent thin workpieces from bending. For longer life, each insert has three cutting edges—when one edge dulls, rotate to the next one. They have chip breakers to stop long chips from forming, so they won’t block the flow of coolant or damage your tool. 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.
