Coated with AlTiN via a PVD process, the insert delivers moderate wear resistance and toughness across a broad range of workpiece materials. The 35-degree diamond (rhombic) shape provides a sharp, positive rake angle of 15 degrees and a honed cutting edge for clean surface finishes. With a 0.0079-inch corner radius and a maximum depth of cut of 0.0492 inches, this insert is optimized for light finishing passes rather than heavy roughing. It is installed using a screw-on holding method and carries a neutral hand orientation, making it adaptable to a variety of toolholder configurations used by professional machinists and tooling technicians.\u003c\/p\u003e\u003cp\u003eThis insert is suited for finishing applications including turning, facing, boring, back turning, and back boring. Primary target workpiece materials are steel, stainless steel, and superalloys and titanium, with secondary suitability for cast iron, aluminum, and other non-ferrous materials. The KCU25 grade with its PVD AlTiN coating is particularly well matched to interrupted cuts and applications where edge security and surface finish quality are both critical. It conforms to both ANSI insert code VBMT3305 and ISO insert code VBMT160402, allowing direct cross-reference against standard toolholder catalogs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN PVD coating provides moderate wear resistance and toughness for steel, stainless steel, cast iron, aluminum, and superalloys\u003c\/li\u003e\n\u003cli\u003e35-degree diamond insert shape with positive rake angle of 15 degrees for reduced cutting forces during finishing\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style delivers consistent surface finish quality on precision turning operations\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method with a 0.1732-inch hole diameter for secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eFP chip breaker geometry optimized for finishing chip control at light depths of cut\u003c\/li\u003e\n\u003cli\u003eDual-standard compliance with ANSI VBMT3305 and ISO VBMT160402 for broad toolholder compatibility\u003c\/li\u003e\n\u003cli\u003e2 cutting edges per insert maximize usable life per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eConforms to ANSI insert code VBMT3305 and ISO insert code VBMT160402.

Ensure the toolholder pocket and seating surfaces are clean and free of debris before seating the insert to maintain accurate edge height and runout. Use the manufacturer-specified torque driver for the screw-on fastener to avoid insert rocking or premature edge failure. Index or replace the insert when surface finish quality or dimensional accuracy degrades, and do not continue cutting on a visibly chipped or worn edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VBMT3305\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VBMT160402\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: V - Diamond (Rhombic) 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: KCU25\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: FP (Finishing)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.61 mm \/ 1.3076 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0079 inches (1\/128 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inches (1.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\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\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 3769466\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749601444146,"sku":"3769466","price":222.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d5163d9ece0b5f7e317f6df3852cf53.jpg?v=1788908203","url":"https:\/\/voomisupply.com\/products\/kennametal-3769466-vbmt3305fp-kcu25-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
