Walter 7178820 Carbide Cutoff Insert 2 Mm Grooving Parting

Product Description

The WALTER 7178820 is a carbide cutoff and grooving insert in the GX-E-CK8 series, identified by ISO code GX16-1E200N02-CK8 WK1. It features a 2.00 mm cutting width, a neutral lead angle, and an uncoated bright finish in manufacturer grade WK1. The CK8 chipbreaker geometry and 21-degree relief angle are engineered for precise material separation in grooving and parting operations. At 0.654 inches overall length and 0.079 inches overall width, this insert fits standard GX-series toolholders. It is a multi-use tool suitable for production turning environments where consistent chip control and dimensional accuracy are required.

This insert is intended for grooving and parting applications on CNC and manual turning centers. Primary workpiece material is non-ferrous metal, with secondary suitability for superalloys. Typical applications include groove profiling, part-off operations, and face grooving where a neutral hand orientation is needed. The WK1 grade and CK8 chipbreaker make it well-suited for finishing and light interrupted cuts on non-ferrous and superalloy components. Machinists and tooling specialists in aerospace, precision manufacturing, and general metalworking environments will find this insert appropriate for demanding turning setups.

Key Features

• 2.00 mm cutting width with 0.20 mm corner radius for precise groove geometry
• Neutral lead angle and neutral hand orientation for versatile toolholder mounting
• CK8 chipbreaker geometry optimized for non-ferrous and superalloy workpieces
• 21-degree relief angle reduces rubbing and supports clean parting cuts
• Uncoated bright finish retains sharp edge integrity on sensitive materials
• Multi-use insert compatible with GX-E-CK8 series toolholders

Compatibility

Designed for use with GX-E-CK8 series toolholders. Conforms to ANSI and ISO standards as specified by ISO code GX16-1E200N02-CK8 WK1. Verify toolholder seat geometry against the GX insert style before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians on CNC or manual turning equipment. Ensure the machine spindle is fully stopped and all energy sources are locked out before changing inserts. Use the correct torque wrench and clamping screw specified for GX-series toolholders - do not overtighten by feel alone. Inspect the insert pocket for wear or debris before seating the new insert to maintain proper geometry and runout.
