It carries the NPL51 insert style designation with ISO code KCGX110304L15 and is coated with TiN via a PVD process using manufacturer grade KC730, a wear-resistant grade suited for P10, P20, M10, M20, S10, and S20 material classifications. The insert features a parallelogram shape, a negative rake geometry, a 55-degree included angle, and four cutting edges, making it a productive choice for profiling and turning operations in CNC and manual turning centers. Licensed machinists and CNC operators install and index this insert during scheduled tooling maintenance.\u003c\/p\u003e\u003cp\u003eThis insert is designed for profiling and turning applications on ferrous and exotic workpiece materials including steel, stainless steel, and superalloys and titanium. With a maximum depth of cut of 0.1250 inches and a compact inscribed circle of 0.2500 inches, it suits finish and semi-finish turning passes where edge geometry control is critical. The left-hand configuration directs cutting forces appropriately for specific toolholder orientations in the Top Notch series. It is screw-held and uses a common chipbreaker geometry compatible with standard insert pockets in that series.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD TiN coating for extended wear life on steel and superalloy workpieces\u003c\/li\u003e\n\u003cli\u003eKC730 grade rated for P10, P20, M10, M20, S10, and S20 material classifications\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert for reduced per-edge cost\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation with screw-held mounting for secure clamping\u003c\/li\u003e\n\u003cli\u003e0.0156-inch corner radius provides controlled surface finish on profiling passes\u003c\/li\u003e\n\u003cli\u003eParallelogram shape with 55-degree included angle and negative rake for stable cutting geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series toolholders accepting NPL51 style inserts.

Power down and lock out the machine spindle before seating or replacing any insert. Use the correct torque wrench and insert screw specified by the toolholder manufacturer to secure the clamping screw — do not overtighten or use improvised drivers. Inspect the insert pocket and clamping screw for wear or debris before seating a new edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NPL51\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: KCGX110304L15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\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: KC730\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade Classifications\u003c\/strong\u003e: P10, P20, M10, M20, S10, S20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Parallelogram\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.3750 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1250 inches (3.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (0.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Common\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Profiling, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0073 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 1163217\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748555522354,"sku":"1163217","price":186.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8675d44c68df95a6e4a8689ae23ccfbe.jpg?v=1788895176","url":"https:\/\/voomisupply.com\/products\/kennametal-1163217-npl51-kc730-profiling-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
