Walter 7169771 Cutoff Insert 3mm Grooving Parting

Product Description

The WALTER 7169771 is a solid carbide cutoff and grooving insert in the SX-E-CK8 series, designed for precision parting and grooving operations on CNC lathes and turning centers. The insert carries the ISO code SX-3E300N02-CK8 WK1 and features a 3mm (0.118 inch) cutting width with a 0.2mm (0.008 inch) corner radius. It is uncoated and runs in a neutral hand orientation with a 23-degree relief angle. The WK1 manufacturer grade and CK8 chipbreaker geometry make this insert well suited for demanding finishing and parting cuts. Licensed machinists and CNC operators are the primary installers of this tooling.

This insert is rated for primary use on non-ferrous metals (ISO material code N) and is also applicable to superalloys (ISO material code S). It is a multi-use insert suitable for grooving and parting applications in production turning environments, including both light-duty and precision finishing passes. The SX-E-CK8 series is engineered for stable, repeatable performance in tight-tolerance cutoff work where chip control and edge consistency are critical.

Key Features

• 3mm cutting width (0.118 inch decimal equivalent) for precise grooving and parting
• Solid carbide substrate in uncoated WK1 grade for non-ferrous and superalloy workpieces
• CK8 chipbreaker geometry for controlled chip evacuation during cutoff operations
• Neutral insert hand and neutral lead angle for versatile mounting orientation
• 23-degree relief angle for reduced cutting forces and improved clearance
• 0.2mm corner radius for sharp, defined groove edges and parting lines
• Compliant with ANSI and ISO standards; ISO code SX-3E300N02-CK8 WK1

Compatibility

Designed for use with Walter SX-E-CK8 series toolholders and grooving systems. Verify toolholder seat specifications before installation to confirm proper insert seating and clamping.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be fully stopped and locked out before changing inserts. Use the correct torque wrench and insert clamp screw to seat the insert firmly without overtightening. Inspect the insert pocket for debris or damage before seating a new insert to ensure accurate positioning and safe operation.
