High-Performance Grooving Carbide Inserts
Individual Carbide Insert Case
Cut grooves on both the inside and outside of a workpiece with the same insert. These inserts are compatible with top-notch style threading and grooving systems, which use a highly rigid clamping design, resulting in a smoother finish and superior tool life. When the edge on one face dulls, flip the insert over. Pair these inserts with a holder (sold separately) with a shank size that fits your machine and workpiece setup. Larger shanks are more stable, while smaller shanks fit into tighter spaces and allow for finer cuts.
Right-hand inserts pair with right-hand external or left-hand internal holders. Left-hand inserts pair with left-hand external or right-hand internal holders.
Round-nose inserts are a good choice for creating smooth, rounded grooves. They’re useful for O-ring grooves, where a sharp corner may damage the O-ring during installation.
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.

High-Performance Carbide Insert Holders for Internal Threading and Grooving
Pair these holders with a threading insert or a grooving insert to make cuts on the inside of a hollow workpiece. Their highly rigid clamping design results in a smoother finish and superior tool life. They are compatible with top-notch style threading and grooving systems. Coolant holes within these holders direct coolant from your machine onto your workpiece, minimizing heat while threading or grooving. Coolant also helps flush out chips, preventing clogging and extending tool life.
Use a right-hand internal holder with a left-hand insert when the workpiece is rotating counterclockwise (toward the lathe operator). Use a left-hand internal holder with a right-hand insert when the workpiece is rotating clockwise (away from the lathe operator).
Carbide holders are more rigid than steel holders, so they vibrate less and leave a smoother finish.

Quick-Change Lathe Tools and Holders
Reduce tooling setup time—install the holder once and alternate between applications by switching out the bit. Once the holder has been aligned with the centerline of the lathe, the locking system ensures alignment repeatability from tool to tool.
