Walter 6427097 Carbide Cutoff Insert 4mm WSM43S

Product Description

The WALTER 6427097 is a solid carbide cutoff and grooving insert designed for demanding material removal in grooving and parting applications. Carrying the ISO code SX-4E400N02-CE4 in grade WSM43S, this insert features a TiAlN/Al2O3/Al multilayer PVD coating applied through the Tiger-tec Silver process. It delivers a 4.00 mm (0.1575 inch) cutting width with a 0.20 mm (0.0079 inch) corner radius. The CE4 chipbreaker geometry and neutral lead angle make it well suited for machining superalloys and a broad range of ferrous and stainless materials. Licensed machinists and CNC tooling technicians are the primary installers.

This insert is built for grooving and parting operations on CNC lathes and turning centers where consistent chip control and heat resistance are critical. The primary workpiece material rating covers superalloys, steel, and stainless steel, corresponding to ISO material codes S, P, and M. The Tiger-tec Silver PVD coating provides enhanced wear resistance at elevated cutting temperatures, making the insert effective on difficult-to-machine alloys common in aerospace and energy sector components. The single-end, clamp-held design integrates with compatible SX-system toolholders.

• Rated for superalloy, steel, and stainless steel workpieces (ISO codes S, P, M)
• Compliant with ANSI and ISO insert standards

Compatibility

Designed for use in SX-system clamp-style toolholders compatible with the SX-4E400N02 insert seat designation. Verify toolholder pocket geometry and clamp style before installation. No additional model-specific compatibility data was provided in the product documentation.

Installation Notes

This insert is installed and changed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing any insert. Use the manufacturer-recommended torque driver for the clamping screw to ensure proper seating without cracking the carbide. Inspect the insert pocket and clamp for wear or debris before each insert change.
