It is built for external grooving and parting operations on CNC lathes and turning centers. The insert features an 8 mm cutting width, a maximum depth of cut of 4 mm, and a neutral hand orientation, making it interchangeable in symmetrical Cut-Grip toolholders. A PVD-applied TiCN plus TiN multilayer coating delivers wear resistance and a low-friction surface that extends tool life across a broad range of workpiece materials. The double-ended design provides two usable cutting edges per insert, reducing cost per edge for high-volume turning shops.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for grooving, profiling, and parting applications on materials classified under ISO workpiece codes K, M, N, and S, covering cast irons, stainless steels, non-ferrous alloys, and heat-resistant superalloys. The Y chip breaker geometry promotes controlled chip formation at positive rake angles, which is particularly useful when machining gummy or stringy materials. It fits within ISCAR Cut-Grip series toolholders designed for the 840 insert size and is appropriate for both production turning and job-shop environments where a single insert grade must handle varied material types.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8 mm cutting width with a 4 mm maximum depth of cut for standard grooving operations\u003c\/li\u003e\n  \u003cli\u003eIC220 solid carbide grade with PVD TiCN plus TiN coating for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation fits left-hand and right-hand Cut-Grip toolholders interchangeably\u003c\/li\u003e\n  \u003cli\u003eDouble-ended insert provides two cutting edges per unit\u003c\/li\u003e\n  \u003cli\u003eY chip breaker with 7-degree positive rake angle for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eFull radius corner equal to 4 mm supports full-radius grooving profiles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in ISCAR Cut-Grip series toolholders accepting the 840 insert size.

Seat the insert fully in the toolholder pocket and verify clamping torque matches the toolholder manufacturer specification before resuming cutting. Inspect the pocket and clamping screw for debris or damage each time the insert is indexed. Follow the machine tool builder and toolholder manufacturer guidelines for approach angle and overhang limits to avoid chatter or premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: GDMY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 840\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.1811 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 4 mm full radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC220\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Finish\u003c\/strong\u003e: TiCN, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Y\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: K, M, N, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Cut-Grip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6401882\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51737121128754,"sku":"6401882","price":456.17,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5da2a2e00dcdd8a32de065516d6a96dc.jpg?v=1788784552","url":"https:\/\/voomisupply.com\/products\/iscar-6401882-grooving-insert-gdmy840y-ic220-8mm-neutral","provider":"Voomi Supply","version":"1.0","type":"link"}
