Cutoff and Grooving Carbide Inserts

Attach these carbide inserts to a holder to perform cutoff and grooving tasks on a lathe.
C2 carbide inserts resist abrasion and are less likely to chip or crack than C5 carbide inserts when cutting aluminum, brass, and bronze. C5 carbide inserts hold up better than C2 carbide inserts when making cuts in steel, stainless steel, and cast iron. Titanium nitride (TiN) coated inserts last longer than uncoated inserts, and you can run them at faster speeds.
Neutral inserts have a 0° lead angle for cutting solid workpieces. Both right- and left-hand inserts have an 8° lead angle for cutting hollow workpieces, such as pipe and tubing. Use right-hand inserts when the workpiece is rotating counterclockwise, or toward you. Use left-hand inserts when the workpiece rotates clockwise, or away from you.
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.
Blade-style holders (sold separately) require a tool block for mounting.

Shank-Style Holders for Cutoff and Grooving Carbide Inserts

Fit these holders directly into a lathe tool post or appropriately sized holder without the need for a tool block. Pair with a carbide insert (sold separately) to make the exact cutoff and grooving tool you need. These holders have a tapered opening at one end.

Combine a holder and carbide insert to perform cutoff and grooving tasks on a lathe.
Neutral inserts have a 0° lead angle for cutting solid workpieces.
Right-hand inserts have an 8° lead angle for cutting hollow workpieces such as pipe and tubing.
C2 carbide is abrasion resistant and less likely to chip or crack than C5 carbide when cutting aluminum, brass, and bronze.
C5 carbide holds up better than C2 carbide when making cuts in steel, stainless steel, and cast iron.
Coated inserts last longer and can be run at faster speeds than uncoated inserts.
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.

Blade-Style Holders for Indexable Cutoff and Grooving Carbide Inserts

Install one of these holders into a tool block for right- and left-hand mounting in a lathe. Pair with a carbide insert (sold separately) to make the exact cutoff and grooving tool you need. These holders have an opening at each end.
Use an insert extractor (sold separately) to change out inserts in the holder.

Cut square corner grooves in a workpiece or cut completely through a part. Pair an insert with a compatible holder. When the first cutting edge dulls, flip the insert to use the other edge, giving it twice the life of a standard cutoff and grooving insert.
