It features an 80-degree diamond (rhombic) shape with a 0.5-inch inscribed circle and a 1\/64-inch (0.0156-inch) corner radius. The insert is coated via CVD with a multilayer TiC, TiCN, and TiN stack, providing moderate wear resistance and toughness across a range of workpiece materials. The flat-top chip breaker geometry, positive rake, and positive side clearance make this insert suitable for turning, facing, and boring operations. It is installed by machinists and CNC operators working with steel and stainless steel in production environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning, facing, and boring of steel, stainless steel, and cast iron, as well as special and super alloys. The KC850 grade with CVD multilayer coating addresses moderate to demanding cutting conditions where a balance of wear resistance and toughness is required. The neutral hand orientation allows flexible setup in standard CPG-style toolholders. Maximum depth of cut is 1.25 mm (0.0492 inches). Applications span both roughing passes at shallow depths and general-purpose finishing on a variety of ferrous and difficult-to-machine materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer TiC, TiCN, and TiN coating for extended tool life across steel, stainless steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (ANSI CPG421, ISO CPG120304) with positive rake and positive side clearance\u003c\/li\u003e\n  \u003cli\u003e0.5-inch inscribed circle and 0.5077-inch insert length for use in standard CPG-series toolholders\u003c\/li\u003e\n  \u003cli\u003eFlat-top chip breaker with honed cutting edge — suitable for turning, facing, and boring in one insert\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method with 2 cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eKC850 grade rated for steel (P), stainless steel (M), cast iron (K), and special\/super alloys (S) at moderate-to-high toughness\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CPG-style insert toolholders accepting a 0.5-inch inscribed circle, 80-degree diamond (C-shape) insert with clamp-style holding.

Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert fully against the toolholder pocket and torque the clamp per the toolholder manufacturer specification. Inspect the insert seating and cutting edge condition before resuming operation; do not use an insert that shows chipping, cratering, or edge deformation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CPG421\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CPG120304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC850\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiC, TiCN, TiN (CVD Multilayer)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 12.90 mm (0.5077 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Positive Rake Geometry)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel (P), Stainless Steel (M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Cast Iron (K), Special\/Super Alloys (S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENDEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0441 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1183482\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749310234930,"sku":"1183482","price":227.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cdfff1bd0c643c7384af4b9ffd763d5d.jpg?v=1788904367","url":"https:\/\/voomisupply.com\/products\/kennametal-1183482-cpg421-kc850-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
