Cubic Boron Nitride Lathe Tool Inserts for Hardened Steel

Resisting wear and fractures when cutting hardened steel, these cubic boron nitride inserts last longer than carbide inserts. Use them for high-speed finishing and interrupted cutting applications. All have multiple cutting edges, so when an edge dulls, rotate the insert in your holder to use a sharp edge. Those with larger nose angles and tip radii have stronger cutting edges, but create more vibration and a rougher finish.

For traceability, inserts come factory sealed from the manufacturer.

VBGW (Diamond with 35° Nose Angle)—For SVJB, SVPB, SVUB, SVVB, SVZB, and SVZC Holders

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 of the inserts.

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.

Precision Lathe Tool Insert Holders for Machining Small Parts

Insert Shown Installed

(Not Included)

Pair these holders with precision carbide inserts to cut fine details and shape small parts. Designed for use in precision lathes, also called Swiss lathes, they fit directly into a tool holder or post—no tool block needed. All are S-code holders, which means the insert is secured with a screw. They’re the most common holder used with positive-rake inserts. Also known as indexable insert holders.

Choose a holder that matches the insert style and inscribed circle diameter (IC) of your insert.
