Designed for the Series A4 tooling platform, it features a G250GMN chip breaker geometry and a neutral hand orientation. The cutting width measures 0.25 inches (6.35 mm), and the maximum depth of cut reaches 0.187 inches (4.75 mm). The KCU25 grade combines a tough carbide substrate with the wear resistance of an aluminum titanium nitride coating, making it suited for interrupted cuts and demanding grooving operations on a range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in external and face grooving applications on CNC lathes and turning centers. The GMN chip breaker geometry promotes chip control in medium to finish grooving passes. The 90-degree included angle and 0.031-inch (0.79 mm) corner radius support clean groove-wall definition. It is a multi-use insert appropriate for production turning environments where consistent groove geometry and surface finish are required. Machinists and CNC operators working in metalworking shops, aerospace, and general manufacturing will find this insert applicable to a broad range of grooving tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCU25 solid carbide grade with PVD-applied AlTiN coating for extended tool life in abrasive and interrupted-cut conditions\u003c\/li\u003e\n  \u003cli\u003eGMN chip breaker geometry for effective chip control during grooving operations\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard Series A4 grooving toolholders\u003c\/li\u003e\n  \u003cli\u003e0.25-inch (6.35 mm) cutting width with a maximum depth of cut of 0.187 inches (4.75 mm)\u003c\/li\u003e\n  \u003cli\u003e0.031-inch (0.79 mm) corner radius for defined groove-wall transitions\u003c\/li\u003e\n  \u003cli\u003eMulti-use insert design supports repeat use across compatible tooling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Series A4 grooving toolholders.

Verify the insert seats fully and evenly in the toolholder pocket before clamping. Do not exceed the rated maximum depth of cut of 0.187 inches (4.75 mm). Inspect the insert edge condition and seating surface between tool changes to avoid premature failure or dimensional error.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.187 inches (4.75 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.150 to 0.200 inches (4.00 to 5.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 0.225 inches (5.72 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.181 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.031 inches (0.79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 9.6 x 5.2 x 1.7 inches\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: 4114340\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728174711090,"sku":"4114340","price":573.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eaf03575dc73446d6f8d31792067066a.jpg?v=1788688973","url":"https:\/\/voomisupply.com\/products\/kennametal-4114340-grooving-insert-kcu25-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
