Manufactured to the NR4062 style in the Top Notch series, it carries a K68 grade uncoated bright finish suited for machining cast iron, hardened steels, and abrasion-resistant materials where a coated insert would wear prematurely. The insert delivers a cutting width of 0.125 inches (3.18 mm) and a maximum depth of cut of 0.150 inches (3.81 mm), with a full-radius geometry and a corner radius of 0.063 inches (1.59 mm). Neutral rake geometry supports consistent chip control across a range of feed rates. This insert is used by machinists and toolroom technicians on production and job-shop turning equipment.\u003c\/p\u003e\n\u003cp\u003eThe KENNAMETAL 1113525 fits insert seat size 4 Top Notch toolholders and is intended for grooving applications in both production environments and job-shop settings. The K68 carbide grade is particularly well matched to interrupted cuts and abrasive workpiece materials where toughness and wear resistance are priorities. The uncoated bright finish maintains sharp edge integrity on fine-finish grooving passes. Right-hand cutting orientation suits standard spindle rotation setups on most CNC and manual lathes. The insert height is 0.453 inches, consistent with Top Notch system geometry requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide K68 grade construction  -  uncoated bright finish for abrasion-resistant and cast iron workpieces\u003c\/li\u003e\n  \u003cli\u003eCutting width of 0.125 inches (3.18 mm) with a full-radius profile and 0.063-inch (1.59 mm) corner radius\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.150 inches (3.81 mm); depth of cut range spans 3.00 mm to 4.00 mm\u003c\/li\u003e\n  \u003cli\u003eNeutral rake geometry for consistent chip formation across varied feed conditions\u003c\/li\u003e\n  \u003cli\u003eRight-hand insert orientation for standard CNC and manual lathe configurations\u003c\/li\u003e\n  \u003cli\u003eTop Notch series, insert seat size 4  -  direct replacement reference NR4062R\/L\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series insert seat size 4 toolholders.

Power down and lock out the machine spindle before seating or removing inserts. Ensure the insert pocket and seating surfaces are clean and free of chips or debris before clamping to maintain proper insert orientation and prevent premature edge failure. Follow the toolholder manufacturer's clamping torque guidance for the Top Notch system  -  do not overtighten the clamp screw, as carbide inserts are brittle and susceptible to fracture under uneven clamping load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\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: C3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.1252 inches (3.18 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.150 inches (3.81 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.150 to 0.200 inches (3.00 to 4.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0626 inches (1.59 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 4062\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Height\u003c\/strong\u003e: 0.453 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 1113525\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740019589426,"sku":"1113525","price":322.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ceff9dc7ade6d49da783c064b3bc5cff.jpg?v=1788821520","url":"https:\/\/voomisupply.com\/products\/kennametal-1113525-grooving-insert-nr4062-k68-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
