Manufactured to the G0305GMN geometry with a KCU10 grade, this insert features a PVD-applied AlTiN coating that improves wear resistance and thermal stability during interrupted or continuous cuts. The neutral hand orientation makes it compatible with both left- and right-hand toolholders. With a 3.05 mm cutting width and a maximum depth of cut of 3.51 mm, it is suited for tight-tolerance groove profiles in production turning environments. Machinists and CNC operators working in job shops or high-volume facilities are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is used in metalcutting applications where controlled groove width and depth are required. The A4 series geometry with the GMN chip breaker is engineered for consistent chip control across a range of workpiece materials, including steels and alloys. Its 90-degree included angle and 0.20 mm corner radius support repeatable groove profiles with minimal burring. The multi-use designation means the insert can be indexed or repositioned for extended service life per edge.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU10 grade with PVD AlTiN coating for enhanced wear and heat resistance\u003c\/li\u003e\n\u003cli\u003e3.05 mm cutting width with a maximum depth of cut of 3.51 mm\u003c\/li\u003e\n\u003cli\u003eGMN chip breaker geometry for reliable chip evacuation in grooving operations\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with left- and right-hand toolholders\u003c\/li\u003e\n\u003cli\u003e0.20 mm corner radius for precise groove profile control\u003c\/li\u003e\n\u003cli\u003eMulti-use insert design for extended edge utilization\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Series A4 grooving toolholders accepting G-style inserts with a 0305 insert size.

Ensure the machine spindle is fully stopped and the turret is in a safe index position before seating or replacing the insert. Use the appropriate torx or hex key specified by the toolholder manufacturer to achieve proper clamping torque. Inspect the insert pocket for chips or debris before seating to prevent micro-fracture from improper seating.\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 3.05 mm (0.1201 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\u003eMaximum Depth 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: 4.01 mm (0.1580 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\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0305\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.7874 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GMN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 9.6 inches L x 5.2 inches W x 1.7 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.007 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 4034773\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749369610546,"sku":"4034773","price":482.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da5ba8fce20f84f3eaa48b868e211cf5.jpg?v=1788905118","url":"https:\/\/voomisupply.com\/products\/kennametal-4034773-grooving-insert-g0305gmn-kcu10-series-a4","provider":"Voomi Supply","version":"1.0","type":"link"}
