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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.00 mm cutting width with 0.20 mm corner radius for precise groove geometry\u003c\/li\u003e\n  \u003cli\u003eNeutral lead angle and neutral hand orientation for versatile toolholder mounting\u003c\/li\u003e\n  \u003cli\u003eCK8 chipbreaker geometry optimized for non-ferrous and superalloy workpieces\u003c\/li\u003e\n  \u003cli\u003e21-degree relief angle reduces rubbing and supports clean parting cuts\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish retains sharp edge integrity on sensitive materials\u003c\/li\u003e\n  \u003cli\u003eMulti-use insert compatible with GX-E-CK8 series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with GX-E-CK8 series toolholders.

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.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 2.00 mm (0.079 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 16.60 mm (0.654 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 2.00 mm (0.079 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm (0.008 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 21 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle Direction\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: GX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1E200N02\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: WK1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: CK8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Superalloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: GX-E-CK8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Grooving, Parting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.002 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7178820\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":51997034774834,"sku":"7178820","price":452.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/abcd814ba1ec8d7366e1c8db03fd325c.jpg?v=1789993788","url":"https:\/\/voomisupply.com\/products\/walter-7178820-carbide-cutoff-insert-2-mm-grooving-parting","provider":"Voomi Supply","version":"1.0","type":"link"}
