Built to the ER-P insert style with a GUP chip breaker geometry, it carries a KCU25 grade designation and an AlTiN coating applied via PVD process. The insert delivers a 4.76 mm cutting width and a maximum depth of cut of 2.62 mm, making it well suited for fine-tolerance grooves in steel and other materials. It is installed and replaced by CNC machinists and tooling technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert fits within the KENNAMETAL Beyond Evolution series, a line engineered for consistent chip control and extended tool life in turning applications. It is intended for metric-measurement tooling setups and carries a neutral hand orientation, making it compatible with standard neutral-hand grooving toolholders. Typical applications include external groove cutting, undercutting, and plunge operations on medium to small-diameter workpieces in production turning environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with AlTiN PVD coating for wear resistance and thermal stability\u003c\/li\u003e\n  \u003cli\u003eKCU25 manufacturer grade optimized for grooving in steel materials\u003c\/li\u003e\n  \u003cli\u003eGUP chip breaker geometry with positive 10-degree rake angle for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003e4.76 mm cutting width with full corner radius of 2.38 mm for smooth groove profiles\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut range of 2.00 mm to 3.00 mm for precise grooving control\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard neutral grooving toolholder systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER-P style neutral-hand grooving toolholders accepting insert seat size 4 within the KENNAMETAL Beyond Evolution series tooling system.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified CNC machinists or tooling technicians with the machine in a full stop and lockout-tagout procedures applied before changing inserts. Seat the insert firmly into the toolholder pocket and torque the clamping screw to the toolholder manufacturer specification. Inspect the insert seat for chips or debris before seating to ensure proper contact and runout accuracy. Replace the insert at first sign of edge wear to avoid workpiece damage or dimensional deviation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: ER-P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GUP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer 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\/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: 4.76 mm (0.1870 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 2.62 mm (0.1030 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 2.00 mm to 3.00 mm (0.1000 to 0.1500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 2.38 mm (0.0940 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 4.43 mm (0.1740 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 4.76 mm (0.187 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1740 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.399 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Beyond Evolution\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.01019 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.76 inches (L) x 0.67 inches (W) x 0.67 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 5988814\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":67913619112242,"sku":"5988814","price":171.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/98bde4a57a7c130b0668e20952699978_fad6050a-c543-491b-95b2-f0bf08f8b2c6.jpg?v=1791246279","url":"https:\/\/voomisupply.com\/products\/kennametal-5988814-grooving-insert-kcu25-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
