Built to the A4R style in size code 3, it features a 0.1250 inch cutting width and a maximum depth of cut of 0.1080 inches. The insert is coated with aluminum titanium nitride (AlTiN) via a PVD process under KENNAMETAL grade KCU10B, providing wear resistance and thermal stability at elevated cutting temperatures. It is double-ended with two cutting edges, extending tool life per insert. A full corner radius of 0.0625 inches produces a smooth groove floor, and the positive rake geometry promotes clean chip formation. Licensed machinists and CNC turning specialists install and index this insert.\u003c\/p\u003e\u003cp\u003eThis insert suits grooving and parting applications in ferrous and non-ferrous materials where tight groove width tolerances are required. The GMN chip breaker geometry is suited to light to medium feeds on small-diameter grooves in general turning applications. It clamps into A4-series KENNAMETAL toolholders using a clamp-style holding method, making it appropriate for both production turning and job-shop environments where repeatable groove geometry is critical. The neutral hand orientation allows use on standard straight-approach grooving setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA4R insert style with size code 3 fits A4-series clamping toolholders\u003c\/li\u003e\n\u003cli\u003e0.1250 inch cutting width with full corner radius of 0.0625 inches for smooth groove floor\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.1080 inches suitable for shallow precision grooves\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating under grade KCU10B for wear resistance in dry and semi-dry cutting\u003c\/li\u003e\n\u003cli\u003eDouble-ended with two cutting edges, reducing cost per groove\u003c\/li\u003e\n\u003cli\u003ePositive rake and GMN chip breaker geometry for controlled chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement grooving insert for KENNAMETAL A4-series clamping-style grooving toolholders accepting size 3 inserts with a 0.1250 inch seat width.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA qualified machinist or CNC tooling technician should install this insert. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate KENNAMETAL clamp key or torx driver to seat the clamp securely against the insert without overtightening. Inspect the insert pocket and clamp for wear or debris before seating a new insert to ensure proper support and accurate groove geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: A4R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.1250 inches (3.180 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1080 inches (2.73 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0625 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\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GMN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.7880 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1250 inches (3.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0.000 degrees\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: 7097847\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742789271858,"sku":"7097847","price":484.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/125fcd7c5d8967bf020a97fd6ec02422.jpg?v=1788839404","url":"https:\/\/voomisupply.com\/products\/kennametal-7097847-grooving-insert-a4r-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
