It carries the NPR508 insert style designation and is manufactured to ISO code KCGX110302R15. The insert features a KCU10 grade with a PVD coating process, a parallelogram shape with a 55-degree included angle, and a negative rake geometry. With a 0.2490-inch inscribed circle and a 0.0080-inch corner radius, it delivers consistent edge geometry suited to precision profiling passes. Right-hand cutting orientation and a screw-in holding method make it straightforward to seat and index. Weighing 0.01 pounds, it is a single-piece packaged insert with a minimum order quantity of 5 units.\u003c\/p\u003e\u003cp\u003eThis insert is intended for profiling and turning applications across a broad range of workpiece materials, including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It is applicable to ISO material groups P, M, K, N, S, and H, covering grade ratings P10, P20, M10, M20, K05, K20, N10, N20, S10, S20, and H10. Typical install scenarios include finish and semi-finish profiling on production turning centers and manual lathes where a Top Notch-style toolholder accepting NPR508 inserts is mounted. The four available cutting edges allow the insert to be indexed before replacement, reducing per-edge tooling cost in high-cycle environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU10 grade with PVD coating process for wear resistance across multiple material groups\u003c\/li\u003e\n\u003cli\u003eParallelogram shape with 55-degree included angle suited to profiling contours and turning passes\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry with 0-degree relief angle for stable cutting under screw-clamping force\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended service life before replacement\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation with common chipbreaker configuration\u003c\/li\u003e\n\u003cli\u003eBroad ISO material group coverage: P, M, K, N, S, and H\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series toolholders that accept NPR508 inserts.

Use the correct torque wrench and screw driver bit specified by the toolholder manufacturer when tightening the clamping screw to avoid insert or pocket damage. Inspect the toolholder pocket and locating surfaces for chips or wear before seating a new insert. Follow the machine tool manufacturer and shop safety guidelines when handling carbide inserts, as edges are sharp and carbide is brittle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NPR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 508\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: KCGX110302R15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Parallelogram\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2490 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.3769 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Height\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0080 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\u003c\/strong\u003e: Negative\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Common\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P10, P20, M10, M20, K05, K20, N10, N20, S10, S20, H10\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: 0.01 pounds\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: 4045418\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742280646962,"sku":"4045418","price":188.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7026f49615817144af98dac8b307fb8.jpg?v=1788836435","url":"https:\/\/voomisupply.com\/products\/kennametal-4045418-npr508-kcu10-carbide-profiling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
