It carries the NPR505 insert style designation and is manufactured to grade K68 using fine grain carbide with an uncoated WC-Co finish. The insert measures 0.125 inches thick, 0.377 inches in length, and 0.249 inches in width, with a corner radius of 0.005 inches. It features a parallelogram shape with a 55-degree included angle, negative rake geometry, a 10-degree rake angle, and zero relief angle. Four cutting edges are available per insert, maximizing tool life and cost-per-edge value.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for profiling and turning operations on non-ferrous metals, superalloys, and titanium workpieces. It is held by screw clamping and is configured for right-hand cutting. The fine grain carbide substrate and uncoated WC-Co surface make it particularly effective in applications where sharp cutting edges and tight tolerances are required, such as aerospace components, medical parts, and precision turned non-ferrous work. It is installed by machinists and CNC operators in production and job shop environments running Top Notch compatible toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNPR505 insert style in K68 fine grain solid carbide for sharp, consistent edge performance on non-ferrous and superalloy materials\u003c\/li\u003e\n  \u003cli\u003eUncoated WC-Co finish maintains edge sharpness without coating buildup, preferred for titanium and non-ferrous cutting\u003c\/li\u003e\n  \u003cli\u003e4 usable cutting edges per insert for extended service life and reduced per-edge cost\u003c\/li\u003e\n  \u003cli\u003eParallelogram shape with 55-degree included angle and 0.005-inch corner radius supports profiling and contour turning\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method for secure, repeatable seating in Top Notch style toolholders\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut rated to 0.1256 inches, suitable for light to medium finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Top Notch series screw-clamp toolholders accepting NPR505 style inserts.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key to seat the clamp screw to the toolholder manufacturer's specified torque range — do not over-torque, as this can fracture the carbide insert. Inspect the insert pocket and clamp for wear or debris before seating a new edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NPR505\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: K68\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide, Fine Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated (WC-Co)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Parallelogram\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.377 inches (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 0.249 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\u003eCorner Radius\u003c\/strong\u003e: 0.005 inches (0.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.249 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1256 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 Angle\u003c\/strong\u003e: 10 degrees (Negative Rake)\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 Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal, Superalloys, 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: KCGX110301R15\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: 0.009 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: 1163311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51753288696114,"sku":"1163311","price":148.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c6a1f7c7bef220c0954f6552fe9f1548.jpg?v=1788935015","url":"https:\/\/voomisupply.com\/products\/kennametal-1163311-npr505-k68-carbide-profiling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
