Walter 6572479 Grooving Insert SX3CE4 WKP23S Solid Carbide

Product Description

The WALTER 6572479 is a solid carbide grooving insert in the SX series, designed for precision groove turning and parting operations on CNC lathes and turning centers. It carries the WKP23S grade designation and features a CVD-applied Al2O3 and TiN coating that improves wear resistance and thermal stability at the cutting edge. The insert has a 3 mm cutting width, a maximum depth of cut of 50 mm, and a CE4 chip breaker geometry with a positive rake angle. The self-grip holding method locks the insert securely into compatible SX toolholders. Licensed machinists and CNC operators install this insert in production and job-shop environments where tight groove tolerances on steel and cast iron are required.

This insert is suited for grooving and recessing operations on steel workpieces (ISO material code P) and cast iron workpieces (ISO material code K) in both light and moderate cutting conditions. The CE4 chip breaker geometry is optimized for controlled chip formation in these materials, making the insert a practical choice for external groove turning on medium to large diameter parts. A positive rake angle reduces cutting forces and heat generation at the insert nose, which extends tool life in continuous grooving passes. The insert is rated for maximum depths of cut exceeding 20 mm, placing it in high-reach grooving applications on shafts, flanges, and similar turned components.

Key Features

• Solid carbide construction with CVD-applied Al2O3 and TiN coating for thermal and abrasion resistance
• 3 mm cutting width with 50 mm maximum depth of cut for deep groove applications
• CE4 chip breaker geometry with positive rake angle for controlled chip formation
• Self-grip insert holding method for secure, repeatable seating in SX series toolholders
• 0.20 mm corner radius for consistent groove floor finish
• Neutral hand orientation for flexible setup on both OD grooving and face grooving operations
• Conforms to ANSI and ISO standards; ANSI and ISO code SX-3E300N02-CE4 WKP23S

Compatibility

Designed for use with SX series self-grip grooving toolholders compatible with size 3 inserts. Primary workpiece materials are steel (ISO code P) and cast iron (ISO code K). Conforms to ANSI and ISO standards per code SX-3E300N02-CE4 WKP23S.

Installation Notes

Installation is performed by CNC machinists or toolroom technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully into the self-grip pocket and confirm it is flush and secure before resuming cuts. Do not exceed the rated maximum depth of cut of 50 mm, and verify toolholder compatibility with insert size 3 SX geometry before mounting.
