Manufactured from uncoated K68 carbide (material grade C3) with a bright finish, this insert delivers consistent performance in applications where a sharp, wear-resistant edge is required. The left-hand configuration provides a 0.125 inch (3.18 mm) cutting width with a maximum depth of cut of 0.150 inch (3.81 mm). The neutral rake geometry and 55-degree included angle support controlled chip flow during grooving passes. Licensed machinists and CNC turning specialists install this insert as part of the Top Notch toolholder system.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for grooving, profiling, and light parting work on lathes running ferrous and non-ferrous materials. The K68 uncoated carbide grade is commonly selected for cuts on cast iron, non-ferrous alloys, and abrasive materials where a coated substrate would offer less edge integrity. It is intended for left-hand toolholder configurations within the Top Notch system. The 0.19 mm corner radius minimizes stress concentration at the groove base while maintaining dimensional accuracy. It is a single-use, non-multi-use insert and must be indexed or replaced when the cutting edge shows wear.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide K68 grade (C3) with bright uncoated finish for sharp edge retention\u003c\/li\u003e\n  \u003cli\u003e0.125 inch (3.18 mm) cutting width for precise groove dimensioning\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut 0.150 inch (3.81 mm); rated range up to 0.200 inch (4.00 mm)\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for compatible Top Notch toolholders\u003c\/li\u003e\n  \u003cli\u003eNeutral rake geometry with 55-degree included angle and 3-degree lead angle\u003c\/li\u003e\n  \u003cli\u003e0.19 mm corner radius for reduced notching and groove-base stress\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KENNAMETAL Top Notch series NG-style toolholders that accept size 3125 left-hand grooving inserts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis insert is installed by a qualified machinist or CNC tooling technician. Shut down the machine spindle and engage all axis locks before seating or replacing the insert. Use the correct Top Notch insert-retention screw and torque to the toolholder manufacturer specification. Inspect the insert pocket and clamping mechanism for debris or damage before each tool change to ensure proper seating and repeatable tool geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3125\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width (Inch)\u003c\/strong\u003e: 0.1252 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width (mm)\u003c\/strong\u003e: 3.18 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut (Inch)\u003c\/strong\u003e: 0.1500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut (mm)\u003c\/strong\u003e: 3.81 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Depth of Cut Range\u003c\/strong\u003e: 0.1500 to 0.2000 inches (3.00 to 4.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius (Inch)\u003c\/strong\u003e: 0.0075 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius (mm)\u003c\/strong\u003e: 0.19 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\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: 0.0291 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: 1113594\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51975704609074,"sku":"1113594","price":235.25,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28c768e97848c284e1a13a17a0fd9099.jpg?v=1789978201","url":"https:\/\/voomisupply.com\/products\/kennametal-1113594-grooving-insert-ng3125-k68-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
