Walter 6393136 Cutoff Insert WSM33S 3mm Carbide

Product Description

The WALTER 6393136 is a solid carbide cutoff and grooving insert carrying the ISO designation SX-3E300N02-CE4 in grade WSM33S, part of the Tiger-tec Silver series. It features a 3.00 mm (0.1181 inches) cutting width with a neutral lead angle and neutral hand orientation, making it suitable for both straight-in parting and grooving operations. The CE4 chipbreaker geometry is designed to manage chip formation in demanding materials. A PVD-applied TiAlN plus Al2O3 plus Al multilayer coating delivers thermal resistance and edge stability. The insert is held in place by a clamp-style toolholder and is designed for single-end use.

This insert is engineered primarily for machining superalloys, stainless steels, and general steels, reflected in its ISO workpiece material codes S, M, and P. Typical applications include grooving and parting operations on CNC turning centers and lathes in production and job-shop environments. The WSM33S grade is matched to material grades S30, M30, and P35, covering a broad range of workpiece hardness and toughness levels. It conforms to both ANSI and ISO standards, supporting use across North American and international tooling systems.

Compatibility

Designed for use with clamp-style toolholders accepting SX-series inserts. Suited for material grades S30, M30, and P35 across ISO workpiece material codes S (superalloys), M (stainless steel), and P (steel).

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine in a locked-out, zero-energy state before any insert change. Seat the insert fully into the toolholder pocket and verify clamp engagement before resuming any cut. Inspect the pocket and clamp for wear or debris that could prevent proper seating. Follow the toolholder manufacturer's clamping procedure for SX-style inserts.
