It carries the K68 fine-grain carbide grade and an uncoated WC-Co finish, making it well-suited for cutting non-ferrous metals, superalloys, and titanium where a sharp, uncoated edge reduces built-up edge and maintains surface finish. The parallelogram-shaped insert measures 0.375 inches in length, 0.25 inches in width, and 0.125 inches in thickness, with a corner radius of 0.0156 inches (0.40 mm). Four cutting edges are available per insert, and the left-hand orientation with a negative rake and zero relief angle suits standard screw-clamped Top Notch toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is intended for profiling and turning applications in metalworking environments — primarily production machining shops, toolrooms, and maintenance machining operations. It targets non-ferrous metal workpiece materials such as aluminum, copper alloys, and brass, as well as superalloys and titanium. The K68 fine-grain carbide grade provides the toughness and edge integrity needed when cutting these demanding materials at controlled feed rates and depths. Maximum depth of cut is 0.125 inches, consistent with its geometry as a profiling insert rather than a heavy roughing tool. Installation requires a compatible Top Notch screw-clamp toolholder accepting an NPL51 insert seat.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFine-grain K68 carbide grade optimized for non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eUncoated WC-Co finish preserves sharp cutting edge geometry for clean surface finishes\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert for extended tool life per unit\u003c\/li\u003e\n\u003cli\u003eParallelogram shape (NPL51) with 55-degree included angle and left-hand orientation\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method compatible with Top Notch series toolholders\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut 0.125 inches with a 0.0156-inch corner radius for profiling work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series screw-clamp toolholders accepting NPL51 insert style seats.

Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key for the insert clamping screw and ensure the seat pocket is clean and free of chips before seating the new insert. Rotating to a fresh cutting edge follows the same lockout procedure.\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\u003eManufacturer Grade\u003c\/strong\u003e: K68\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Fine Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Uncoated WC-Co\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\u003eInsert Thickness\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\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: 0.125 inches\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\u003eRake\u003c\/strong\u003e: Negative\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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal; Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: KCGX110304L15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0088 pounds\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: 5\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: 1163315\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747089056050,"sku":"1163315","price":148.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/874f0c73570e5963c9e99d45afa65927.jpg?v=1788875929","url":"https:\/\/voomisupply.com\/products\/kennametal-1163315-npl51-k68-carbide-profiling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
