Built to the NG insert style in the Top Notch series, it delivers a 4.80 mm (0.189 inch) cutting width and a maximum depth of cut of 3.81 mm (0.150 inch). The K68 grade is an uncoated, bright-finish carbide formulated for cutting non-ferrous and cast materials where a sharp, slick edge is required. With a neutral rake and a 0.57 mm corner radius, this insert produces clean, consistent groove profiles with minimal burring. It is installed and replaced by machinists and CNC tooling technicians as part of scheduled insert rotation.\u003c\/p\u003e\u003cp\u003eThis insert is suited for grooving operations on lathes running non-ferrous metals, cast iron, and similar materials where the K68 carbide grade performs best. The right-hand cutting orientation fits standard Top Notch toolholders configured for right-hand operation. Typical applications include groove turning, undercutting, and parting on medium to short-run production work. The NG3189 insert size positions this part in medium-duty grooving applications where dimensional accuracy and edge consistency are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide K68 grade  -  uncoated bright finish optimized for non-ferrous and cast material applications\u003c\/li\u003e\n\u003cli\u003e4.80 mm (0.189 inch) cutting width for consistent, repeatable groove sizing\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 3.81 mm (0.150 inch); depth-of-cut range spans 3.00 mm to 4.00 mm\u003c\/li\u003e\n\u003cli\u003e0.57 mm (0.0225 inch) corner radius with neutral rake for clean groove-floor finishes\u003c\/li\u003e\n\u003cli\u003eRight-hand insert orientation; NG insert style in the Top Notch series\u003c\/li\u003e\n\u003cli\u003e55-degree included angle with a 3-degree lead angle for controlled chip formation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for Top Notch series toolholders accepting the NG3189 insert style in right-hand configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed by a machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the toolholder pocket and verify the clamping screw torque per the toolholder manufacturer's specification. Inspect the pocket and clamping components for wear or debris before seating a new insert, as a contaminated pocket will affect dimensional accuracy and edge life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3189\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\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 4.80 mm (0.189 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.81 mm (0.150 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth of Cut Range\u003c\/strong\u003e: 3.00 mm to 4.00 mm (0.150 to 0.200 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.57 mm (0.0225 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Height\u003c\/strong\u003e: 0.344 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.029 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: 1113583\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51787087249714,"sku":"1113583","price":233.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/777ebf8f8c211389321eb833ec3402cb.jpg?v=1789209833","url":"https:\/\/voomisupply.com\/products\/kennametal-1113583-grooving-insert-ng3189-k68-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
