Walter 7178822 Cutoff Insert Solid Carbide 3 Mm Grooving

Product Description

The WALTER 7178822 is a solid carbide cutoff and grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. Carrying the ISO code GX24-2E300N02-CK8 WK1, it belongs to the GX-E-CK8 series and features a 3.00 mm cutting width with a neutral lead angle and neutral hand orientation. The CK8 chipbreaker geometry is engineered for controlled chip formation, and the uncoated bright finish makes this insert well suited for non-ferrous metals and superalloys where coating buildup or edge adhesion can cause problems. Licensed machinists and CNC turning specialists are the primary installers of this tooling.

This insert is applied in grooving and parting applications on turning equipment where tight width tolerances and predictable chip evacuation are required. Its primary workpiece material designation is non-ferrous metal (N code), with superalloy (S code) listed as the secondary application. The neutral insert hand allows use in standard right-hand or left-hand toolholders configured for the GX-E series system. It is suited for both production and job-shop environments handling aluminum, copper alloys, titanium, and nickel-based superalloys.

Key Features

• 3.00 mm cutting width (0.1180 inches) for precise groove and parting dimensions
• Solid carbide construction with bright uncoated finish for non-ferrous and superalloy applications
• CK8 chipbreaker for controlled chip formation and reliable chip evacuation
• Neutral lead angle and neutral hand for versatile toolholder compatibility
• 0.20 mm corner radius (0.0080 inches) for reduced stress concentration at groove edges
• Compliant with ANSI and ISO standards

Compatibility

Designed for use in GX-E series toolholders compatible with the GX24-2E insert seat configuration. Multi-use capability confirmed per manufacturer data. Verify toolholder seat size and clamping system before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the turret is in a safe index position before changing inserts. Use the appropriate torque wrench and clamping screw specified by the toolholder manufacturer - do not overtighten or use improvised tools on the clamping screw. Inspect the insert seat and clamping components for wear or debris before seating the new insert.
