It features a 45-degree diamond shape (Insert Shape Code G), a 5\/32 inch (0.1563 inch) inscribed circle, a 0.0156 inch corner radius, and a flat-top chip breaker geometry. The insert carries a positive rake angle and positive side clearance, delivering a balance of wear resistance and toughness across multiple workpiece material groups. It is designed for screw-on mounting and is sold individually with a minimum order quantity of five units. This insert is appropriate for use by machinists and CNC tooling specialists on turning, facing, and boring operations.\u003c\/p\u003e\n\u003cp\u003eThe KENNAMETAL 4050616 is suited for moderate-duty turning, facing, and boring applications on steel, stainless steel, cast iron, aluminum and non-ferrous materials, and superalloys and titanium. The KCU25 grade is rated for moderate wear resistance and toughness across material groups P, M, K, N, and S. With a maximum depth of cut of 0.1472 inches and a honed cutting edge style, this insert performs reliably in both roughing and semi-finishing passes where consistent tool life is required. It conforms to ANSI and ISO standards under industry designations GPHW1211 and ISO code GPHW.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCU25 grade with PVD AlTiN coating for moderate wear resistance and toughness across P, M, K, N, and S material groups\u003c\/li\u003e\n  \u003cli\u003e45-degree diamond insert shape (GPCD51 style) with flat-top chip breaker for chip control in turning and facing\u003c\/li\u003e\n  \u003cli\u003ePositive rake and positive side clearance geometry reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style extends tool life and reduces micro-chipping\u003c\/li\u003e\n  \u003cli\u003eScrew-on holding method ensures repeatable seating and rigid clamping in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert; neutral hand orientation for flexible toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards (ANSI: GPHW1211, ISO: GPHW)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-on style toolholders compatible with ANSI size code 1211 and insert shape code G.

Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert firmly against the toolholder pocket and tighten the clamping screw to the toolholder manufacturer's specified torque. Inspect the insert seating surface and pocket for chips or debris before securing to maintain proper tool geometry and prevent premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Grade\u003c\/strong\u003e: KCU25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\u003eInsert Style\u003c\/strong\u003e: GPCD51 (GPHW)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 45-Degree Diamond (Non-ISO Specialty)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4420 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.0840 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1472 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Positive Geometry)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum and Non-Ferrous, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: GPHW1211\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: GPCD050104\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 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: 4050616\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727718154546,"sku":"4050616","price":176.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9454e493633b752f6077592c0ff91cbd.jpg?v=1788681218","url":"https:\/\/voomisupply.com\/products\/kennametal-4050616-turning-insert-kcu25-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
