Walter 6738341 Cutoff Insert 3mm Grooving Parting

Product Description

The WALTER 6738341 is a solid carbide cutoff and grooving insert in the GX-E-CF5 series, designed for grooving and parting operations on CNC lathes and turning centers. It carries the ISO code GX242E300N02CF5 in grade WSM23S and features a TiAlN/Al2O3/Al PVD coating applied for heat resistance and edge durability at elevated cutting speeds. The cutting width is 3.00 mm (0.118 inches), with a neutral lead angle and a corner radius of 0.20 mm. A 10-degree relief angle supports clean chip clearance. The CF5 chipbreaker geometry is engineered for controlled chip formation in demanding materials.

This insert is rated for superalloy workpiece materials, covering ISO material groups M, P, and S. Those classifications include stainless steels, carbon and alloy steels, and high-temperature superalloys such as nickel- and titanium-based alloys. Typical applications include groove turning, face grooving, and parting off on precision machined components in aerospace, energy, and general industrial manufacturing. The multi-use geometry allows the insert to be repositioned for secondary cuts where toolholder design permits.

Key Features

• Solid carbide substrate with PVD-applied TiAlN/Al2O3/Al coating for wear and oxidation resistance
• 3.00 mm cutting width with neutral lead angle and neutral hand for straight-in grooving
• CF5 chipbreaker geometry engineered for superalloy and stainless steel chip control
• 10-degree relief angle promotes clean edge entry and reduces flank wear
• 0.20 mm corner radius for a controlled groove floor profile
• Conforms to ANSI and ISO insert standards for broad toolholder compatibility

Compatibility

Designed for use in GX-E-CF5 series toolholders accepting insert size code 2E300N02. Conforms to ANSI and ISO standards for grooving inserts. Verify toolholder clamping slot dimensions before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before seating or removing inserts. Use the appropriate torx or hex key specified by the toolholder manufacturer to secure the clamping screw - do not overtighten. Inspect the toolholder pocket and clamping surfaces for chips or debris before inserting, as contamination can cause insert rocking and premature edge failure.
