It carries a multilayer CVD coating of TiC, TiCN, and TiN, which delivers moderate wear resistance combined with high toughness across a broad range of workpiece materials. The insert is square (S-shape) with a 90-degree included angle, a 3\/8-inch inscribed circle, a 1\/64-inch (0.0156 inch) corner radius, and a positive rake angle of 5 degrees. The LF chip breaker geometry is optimized for finishing and light machining passes. It seats via a screw-on (Screw) holding method and is produced to ANSI and ISO dimensional standards.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel, stainless steel, and cast iron, as well as special and super alloys. The KC850 grade with CVD multilayer coating targets moderate to high toughness applications where consistent surface finish is required. Typical users are CNC lathe operators, tool-and-die shops, and production machinists running finishing passes with controlled depth of cut. Maximum depth of cut is 0.0492 inch (1.25 mm). Each insert provides 4 usable cutting edges, making it an efficient choice for high-volume turning cells.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC850 grade with CVD multilayer TiC\/TiCN\/TiN coating for wear resistance and toughness across steel, stainless, and cast iron\u003c\/li\u003e\n\u003cli\u003eLF chip breaker geometry designed for finishing and light machining operations\u003c\/li\u003e\n\u003cli\u003ePositive rake (5 degrees) and positive side clearance reduce cutting forces on workpiece\u003c\/li\u003e\n\u003cli\u003e4 cutting edges per insert maximize tooling value\u003c\/li\u003e\n\u003cli\u003eScrew-on insert holding method ensures rigid, repeatable seating\u003c\/li\u003e\n\u003cli\u003eCompliant with both ANSI (SCMT3251) and ISO (SCMT09T304) standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw-on SCMT-style toolholders conforming to ANSI and ISO standards.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key to torque the clamp screw to the toolholder manufacturer's specification — do not overtighten, as this can crack the carbide insert. Inspect the insert pocket and seating surface for chips or debris before seating a new insert to maintain dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: SCMT3251\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: SCMT09T304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC850\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiC, TiCN, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD (Multilayer)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: S - Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inch (4.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees (Positive)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing, Light Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inch (1.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Special\/Super Alloys\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\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: 0.0079 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1162419\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51735581884722,"sku":"1162419","price":215.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47c08ff8e87f6dfed72242a12e071959.jpg?v=1788773112","url":"https:\/\/voomisupply.com\/products\/kennametal-1162419-scmt3251lf-kc850-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
