It carries the KCU10 manufacturer grade with a PVD-applied AlTiN coating, delivering wear resistance and thermal stability across a range of workpiece materials. The insert features a neutral hand orientation, a 3.18 mm cutting width, and a maximum depth of cut of 3.40 mm. The GMN chip breaker geometry controls chip flow during shallow to medium-depth grooving passes. Machinists and CNC operators install this insert as part of the Kennametal Series A4 grooving system.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for production turning environments where consistent groove geometry and surface finish are required. The 90-degree included angle and 0.20 mm corner radius make it appropriate for sharp-shouldered grooves with minimal burr formation. It is applicable to grooving operations in the 3.00 mm to 4.00 mm depth-of-cut range, covering common snap ring grooves, O-ring grooves, and undercut profiles in both ferrous and non-ferrous materials. The multi-use designation means the insert can be indexed within compatible toolholders to extend usable life per unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCU10 solid carbide grade with PVD AlTiN coating for thermal and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003e3.18 mm cutting width with a maximum depth of cut of 3.40 mm\u003c\/li\u003e\n  \u003cli\u003eGMN chip breaker geometry for controlled chip evacuation during grooving\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for use in standard right-hand and left-hand toolholders where applicable\u003c\/li\u003e\n  \u003cli\u003e0.20 mm corner radius produces sharp-shouldered groove profiles\u003c\/li\u003e\n  \u003cli\u003eSeries A4 designation for use with compatible Kennametal A4 grooving toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Kennametal Series A4 grooving toolholders.

Ensure the machine spindle is fully stopped and the machine is in a safe lockout state before changing inserts. Seat the insert firmly and squarely in the pocket and tighten the clamping screw to the toolholder manufacturer's specified torque using a calibrated torque wrench. Verify insert seating and runout before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 3.18 mm (0.1252 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.40 mm (0.1339 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\u003eCutting Height\u003c\/strong\u003e: 4.02 mm (0.1583 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm (0.0079 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 Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10\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\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 125\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A4\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\u003eWeight\u003c\/strong\u003e: 0.007 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: 4034806\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51735028334898,"sku":"4034806","price":532.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b26a22da530e9351355b74bdd84a668e.jpg?v=1788769418","url":"https:\/\/voomisupply.com\/products\/kennametal-4034806-grooving-insert-kcu10-altin-3-18mm","provider":"Voomi Supply","version":"1.0","type":"link"}
