Manufactured to the G0505GMN geometry in the KCU10 grade, this insert features a Physical Vapor Deposition (PVD) AlTiN coating that provides thermal resistance and wear protection at elevated cutting speeds. The 5.05 mm cutting width and a maximum depth of cut of 4.19 mm make it well suited for medium-depth groove profiles. The neutral hand orientation allows for straightforward straight-plunge grooving. It is installed by machinists and CNC turning specialists in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is used in external grooving, parting, and face grooving applications on a range of workpiece materials including steel, cast iron, and high-temperature alloys. The GMN chip breaker geometry promotes reliable chip control and evacuation, which is critical in grooving operations where chip packing can damage the workpiece or the insert seat. The Series A4 designation places it in a standardized toolholder family. It is suited to both production turning and precision finishing passes where consistent groove width is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU10 solid carbide grade with PVD AlTiN coating for extended tool life in steel and cast iron\u003c\/li\u003e\n\u003cli\u003e5.05 mm cutting width with a maximum depth of cut of 4.19 mm\u003c\/li\u003e\n\u003cli\u003eGMN chip breaker geometry for controlled chip formation and evacuation in grooving operations\u003c\/li\u003e\n\u003cli\u003eNeutral hand insert orientation for straight-plunge grooving setups\u003c\/li\u003e\n\u003cli\u003e0.79 mm corner radius for groove profile accuracy and edge strength\u003c\/li\u003e\n\u003cli\u003eMulti-use insert compatible with Series A4 toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Series A4 grooving toolholders.

Ensure the machine spindle is fully stopped and the turret is locked before seating or replacing the insert. Use the manufacturer-specified torque tool for the clamping screw to avoid cracking the carbide substrate. Inspect the toolholder pocket for wear, chips, or debris before seating the new insert, as a contaminated pocket will affect insert performance and positioning accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert 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\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\u003eInsert Style\u003c\/strong\u003e: G\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: 5.05 mm (0.1988 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 4.19 mm (0.1654 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 4.00 mm to 5.00 mm (0.1500 to 0.2000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 5.72 mm (0.2250 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\u003eOverall Length\u003c\/strong\u003e: 0.9843 inches (25.0 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0505\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 4034788\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51735029317938,"sku":"4034788","price":68.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6eeeaac7a1ee19bfdc4ce9760417537.jpg?v=1788769430","url":"https:\/\/voomisupply.com\/products\/kennametal-4034788-grooving-insert-g0505gmn-kcu10-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
