Manufactured to the G187GMN geometry in the A4 series, it features a 4.76 mm (0.1874 inch) cutting width and a maximum depth of cut of 3.51 mm (0.1378 inch). The insert carries a KCU10 grade designation and is finished with an AlTiN (aluminum titanium nitride) coating applied via a PVD process, providing thermal resistance and wear protection during interrupted cuts and general turning applications. Installation and setup are performed by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis grooving insert is suited for metric-dimensioned toolholders accepting an A4 series insert seat size 4. The neutral hand orientation makes it compatible with straight-plunge grooving operations. The GMN chip breaker geometry is engineered for controlled chip formation across the rated depth-of-cut range of 3.00 mm to 4.00 mm (0.1000 inch to 0.1500 inch). A corner radius of 0.79 mm (0.0312 inch) provides a defined edge break at groove walls. The insert is a multi-use tool, meaning it may be indexed or repositioned per the toolholder design before replacement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU10 solid carbide grade with PVD-applied AlTiN coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eGMN chip breaker geometry for reliable chip control in the 3.00 mm to 4.00 mm depth-of-cut range\u003c\/li\u003e\n\u003cli\u003e4.76 mm cutting width with a 0.79 mm corner radius for precise groove geometry\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation for straight-plunge grooving applications\u003c\/li\u003e\n\u003cli\u003eA4 series, insert seat size 4 for compatibility with corresponding toolholder systems\u003c\/li\u003e\n\u003cli\u003eMulti-use insert design to maximize tooling economy per insert\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in A4 series grooving toolholders accepting insert seat size 4 with a neutral hand orientation.

Use the correct torque wrench and insert clamping hardware specified by the toolholder manufacturer — do not substitute fasteners. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Verify insert seating is flush and secure before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: G\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\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\u003eCutting Width\u003c\/strong\u003e: 4.76 mm (0.1874 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.51 mm (0.1378 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth of Cut Range\u003c\/strong\u003e: 3.00 mm to 4.00 mm (0.1000 to 0.1500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.79 mm (0.0312 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 4.75 mm (0.1870 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.7874 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 187\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.033 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturers Catalog Number\u003c\/strong\u003e: A4G187I04P2GMN\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: 4034809\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738747404594,"sku":"4034809","price":605.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84e21484b12fd6cc8bea56c6c1550602.jpg?v=1788803785","url":"https:\/\/voomisupply.com\/products\/kennametal-4034809-grooving-insert-kcu10-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
