Running the A4G0600GUP geometry in the KCU10 grade, it features a 6 mm cutting width and a maximum depth of cut of 4.5 mm. The AlTiN coating is applied via PVD process, delivering hard-surface wear resistance suited for ferrous and alloy workpiece materials. The insert has a neutral hand orientation and a positive rake angle, reducing cutting forces during grooving passes. Machinists and CNC turning specialists install this insert into compatible A4-series toolholders as a direct replacement unit.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for grooving and light parting applications in both production and job-shop turning environments. The GUP chip breaker geometry is suited for moderate-feed grooving where chip control matters. The 0.80 mm corner radius supports general-purpose groove profiles without a full radius. Material grades C3 and C4 indicate suitability for cast iron, steel, and similar materials at moderate cutting parameters. It is sold individually but carries a minimum order quantity of 10 units, making it appropriate for shop-stock replenishment or toolcrib inventory management.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCU10 solid carbide grade with PVD AlTiN coating for wear resistance on ferrous materials\u003c\/li\u003e\n  \u003cli\u003e6 mm cutting width with a maximum depth of cut of 4.5 mm\u003c\/li\u003e\n  \u003cli\u003eA4G0600GUP geometry: GUP chip breaker with positive rake and neutral hand\u003c\/li\u003e\n  \u003cli\u003e0.80 mm corner radius for general-purpose groove profiles\u003c\/li\u003e\n  \u003cli\u003eNo full radius — suitable for square-shoulder and standard groove forms\u003c\/li\u003e\n  \u003cli\u003eSeries A4 insert style for use with A4-series grooving toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with A4-series grooving and parting toolholders that accept the A4G insert style.

Power down and lock out the machine before changing inserts. Seat the insert fully and evenly in the pocket and secure the clamping screw to the toolholder manufacturer's specified torque range — do not overtighten. Inspect the insert seating and clamping mechanism for chips or debris before each use to prevent insert rocking or premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: A4G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10\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: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 4.50 mm (0.1760 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 4.00 mm to 5.00 mm (0.1500 to 0.2000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.80 mm (0.0315 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.181 inches\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\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GUP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 pounds\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: 3781286\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728992174386,"sku":"3781286","price":545.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f631b2104eabb329e1cfce3bff0d5ba5.jpg?v=1788698521","url":"https:\/\/voomisupply.com\/products\/kennametal-3781286-grooving-insert-kcu10-altin-6mm","provider":"Voomi Supply","version":"1.0","type":"link"}
