Iscar 3335538 Grooving Insert PENTA24N157C IC908 Carbide

Product Description

The ISCAR 3335538 is a solid carbide grooving insert in the PentaCut series, designed for precision grooving and parting operations on CNC lathes and turning centers. It carries the PENTA24N157C IC908 designation and features a TiAlN PVD coating applied over a fine-grain carbide substrate. The insert delivers a cutting width of 1.57 mm (0.062 inches) and supports a maximum depth of cut of 3.00 mm (0.118 inches). The IC908 grade is engineered for thermal resistance and wear resistance across a broad range of workpiece materials. Machinists and tooling specialists working in production turning environments are the primary installers and users of this insert.

This insert is suited for grooving applications across universal workpiece material groups, including ISO material codes H, K, M, P, and S, covering hardened steels, cast irons, stainless steels, carbon and alloy steels, and high-temperature superalloys. The neutral hand orientation makes it usable in standard grooving toolholders without directional restriction. The chip breaker designation C is integrated into the insert geometry to support controlled chip formation during grooving passes. It is appropriate for both light-production and high-volume turning operations where consistent groove width and depth accuracy are required.

Key Features

Compatibility

Designed for use with PentaCut series toolholders accepting the PENTA 24N157 insert size, as identified by ISO code PENTA 24N157C079 IC908. Compatible with workpiece material groups H, K, M, P, and S per ISO classification.

Installation Notes

Installation is performed by a qualified machinist or tooling technician on a CNC lathe or turning center. The machine spindle must be fully stopped and the turret locked before seating or replacing the insert. Use the appropriate torque wrench and ISCAR-specified clamping hardware for the PentaCut toolholder to avoid insert movement or seat damage. Do not exceed the rated maximum depth of cut for the insert size.
