It uses NPL51 geometry with a parallelogram shape, a 55-degree included angle, and four cutting edges per insert, extending tool life between index cycles. The insert is uncoated with a WC-Co (tungsten carbide-cobalt) finish and carries a fine-grain carbide substrate under manufacturer grade K313. A 0.0156-inch corner radius and negative rake geometry make it well suited for controlled chip formation during profiling passes.\u003c\/p\u003e\u003cp\u003eThis insert is intended for profiling and turning operations on non-ferrous metals, superalloys, and titanium — workpiece material codes N and S. Its left-hand cutting orientation suits specific toolholder setups common in production turning environments. The insert seats via screw clamping, consistent with Top Notch-series toolholders. It is typically used in light to moderate profiling applications where tight radius definition and edge integrity are critical. Machinists and CNC setup technicians working on aerospace, medical, or precision-component turning will find this insert suited to those demands.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFour cutting edges per insert for extended indexable service life\u003c\/li\u003e\n\u003cli\u003eFine-grain carbide substrate at grade K313 for edge sharpness on difficult materials\u003c\/li\u003e\n\u003cli\u003eUncoated WC-Co surface — no coating delamination risk on non-ferrous or superalloy workpieces\u003c\/li\u003e\n\u003cli\u003e0.0156-inch (0.40 mm) corner radius for precise profile definition\u003c\/li\u003e\n\u003cli\u003eNegative rake, 0-degree relief angle geometry with common chipbreaker\u003c\/li\u003e\n\u003cli\u003eScrew-mount insert holding for secure, repeatable seating in Top Notch toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series screw-clamp toolholders accepting NPL51 inserts. ISO code KCGX110304L15 and standards NPL51 and KCGX110304L15 are listed for this insert. Verify toolholder seat geometry and hand orientation before ordering.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Power down the machine and engage all safety locks before indexing or replacing inserts. Use the correct Torx or hex key for the clamping screw — do not overtighten, as carbide inserts are brittle and will crack under excessive clamping load. Confirm left-hand orientation matches the toolholder before seating the insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NPL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 51\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Parallelogram\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: Fine Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: K313\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated (WC-Co)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Common\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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\u003eInsert Length\u003c\/strong\u003e: 0.375 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches (3.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Length\u003c\/strong\u003e: 0.375 inches (11.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal; Superalloys and Titanium\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\u003eApplications\u003c\/strong\u003e: Profiling; Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0088 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: 1163284\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51752010088754,"sku":"1163284","price":149.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/03ddabd43e5af6c398af81d8035b8b6a.jpg?v=1788925164","url":"https:\/\/voomisupply.com\/products\/kennametal-1163284-npl51-k313-carbide-profiling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
