This left-hand insert carries the KC730 manufacturer grade and features a PVD-applied TiN coating that extends tool life in demanding P, M, and S workpiece material classes. The parallelogram-shaped insert has a 55-degree included angle, an 8-degree relief angle, a positive rake of 10 degrees, and a 0.0312-inch corner radius. It provides 2 cutting edges per insert and is held in place by a clamp-style toolholder. Licensed machinists and CNC turning specialists are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for profiling and external turning operations in both production and job-shop environments. The KC730 grade targets ISO P10 through P20, M10 through M20, and S10 through S20 material grade ranges, making it applicable to general steel turning, stainless steel finishing, and difficult-to-machine superalloy and titanium cuts. The 0.1250-inch maximum depth of cut and 0.3750-inch insert length make it appropriate for light-to-moderate radial profiling passes on CNC lathes and turning centers. It is cataloged under the Top Notch series and conforms to ISO code KCGR110308L08.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNPGR52 style, left-hand orientation with parallelogram shape and 55-degree included angle\u003c\/li\u003e\n  \u003cli\u003eKC730 grade with PVD TiN coating for extended tool life on steel, stainless, and superalloys\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry (10 degrees) reduces cutting forces on difficult materials\u003c\/li\u003e\n  \u003cli\u003e0.0312-inch (0.79 mm) corner radius suited for profiling with controlled surface finish\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges per insert for cost-effective indexing\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding for secure, repeatable seating in Top Notch toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eConforms to NPGR52L and ISO KCGR110308L08 standards.

Always power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque driver or clamp screw tool specified by the toolholder manufacturer to secure the insert without over-torquing the clamp. Inspect the insert seat and clamp for chips or debris before seating a new insert to ensure accurate tool nose positioning.\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: 52L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC730\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (PVD process)\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: Left Hand\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 (Positive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0312 inches (0.79 mm)\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 Height\u003c\/strong\u003e: 0.1250 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\u003eWidth\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2500 inches\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\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: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Grade\u003c\/strong\u003e: P10, P20, M10, M20, S10, S20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: KCGR110308L08\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: 0.0082 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  \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: 1163233\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732525973810,"sku":"1163233","price":162.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/806607d72f6c06ab80b45fc00eceb5c5.jpg?v=1788744025","url":"https:\/\/voomisupply.com\/products\/kennametal-1163233-npgr52-kc730-carbide-profiling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
