It carries the NPGR51 style designation and is manufactured in the KC850 grade using a CVD coating process. The insert features a parallelogram shape with a positive rake angle of 10 degrees and a relief angle of 8 degrees. With a corner radius of 0.0156 inches and two cutting edges, it delivers controlled chip formation during profiling passes. Licensed machinists and CNC operators install this insert in compatible Top Notch toolholders for finish and semi-finish turning applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for profiling and turning operations on steel (ISO P) and stainless steel (ISO M) workpieces, covering material grades P30, P40, M30, and M40. It is appropriate for both CNC lathe and manual turning setups where a right-hand insert with a shallow corner radius is required. The maximum depth of cut is 0.1250 inches, making it a practical choice for finish profiling passes where dimensional accuracy and surface finish are priorities. Machinists working in job shops, production turning cells, and maintenance machining operations will find this insert fits standard Top Notch clamping systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNPGR51 insert style with KC850 carbide grade for steel and stainless steel cutting\u003c\/li\u003e\n  \u003cli\u003eCVD coating process applied to solid carbide substrate\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry (10-degree rake angle, 8-degree relief angle) reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0156 inches (0.40 mm) for controlled profiling transitions\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert; right-hand hand designation\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method; fits Top Notch series toolholders\u003c\/li\u003e\n  \u003cli\u003e55-degree included angle parallelogram shape for profiling clearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Top Notch series clamping toolholders that accept the NPGR51R insert style.

Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or clamp screw driver specified by the toolholder manufacturer to secure the clamp; do not overtighten. Inspect the insert pocket and clamp for wear or debris before seating a new insert to ensure proper seating and runout control.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NPGR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 51R\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\u003eMaterial Grade\u003c\/strong\u003e: P30, P40, M30, M40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel\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: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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 (Inscribed Circle)\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\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\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 8 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\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: KCGR110304R08\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: 0.0082 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 1163402\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731375980850,"sku":"1163402","price":189.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e760efe13752da3dc5922dd8b27b3f78.jpg?v=1788730169","url":"https:\/\/voomisupply.com\/products\/kennametal-1163402-npgr51-kc850-profiling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
