Built in the A4R insert style with a size code of 4, it features a 0.1590-inch cutting width and a maximum depth of cut of 0.1360 inches. The insert is manufactured from carbide in KENNAMETAL grade KCU10B with an AlTiN coating applied via PVD process, providing high wear resistance and thermal stability across a range of workpiece materials. With two cutting edges per insert, it delivers extended tool life per unit. Licensed machinists and CNC operators working in production turning environments are the typical installers.\u003c\/p\u003e\u003cp\u003eThis insert suits grooving, parting, and undercutting applications in both roughing and finishing contexts. The full-radius geometry with a 0.0797-inch corner radius and GMN chip breaker supports controlled chip formation. The positive rake angle reduces cutting forces, making it well suited for turning steel, stainless, and similar materials where heat management and surface finish are priorities. The neutral hand orientation allows use on both right- and left-hand toolholders within the A4 series system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end insert provides two usable cutting edges for extended tool life\u003c\/li\u003e\n\u003cli\u003eAlTiN coating via PVD process enhances heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eFull-radius geometry with 0.0797-inch corner radius supports smooth groove profiles\u003c\/li\u003e\n\u003cli\u003eGMN chip breaker promotes reliable chip control during grooving passes\u003c\/li\u003e\n\u003cli\u003ePositive rake angle reduces cutting forces on the workpiece\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method ensures rigid, repeatable seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KENNAMETAL A4 series grooving toolholders that accept size 4 inserts with clamp-style holding.

Power down and lock out the machine before changing inserts. Seat the insert fully in the toolholder pocket before tightening the clamp to the toolholder manufacturer specification. Inspect the insert seat and clamp for chips or debris that could affect seating and runout before resuming operation.\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: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.1590 inches (4.050 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1360 inches (3.45 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0797 inches (2.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.7910 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1590 inches\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\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\u003eFull Radius\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\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: 7097828\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51741619880242,"sku":"7097828","price":469.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22e81940885ff72ca94552f6fd676864_695c9304-240d-4450-8316-619263ee9fc9.jpg?v=1788832532","url":"https:\/\/voomisupply.com\/products\/kennametal-7097828-grooving-insert-a4r-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
