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.
