It carries the R0405GMN geometry with a KCU10 grade, featuring a PVD-applied AlTiN coating that provides thermal resistance and extended tool life when cutting steel and difficult alloys. The insert delivers a 4.05 mm cutting width with a maximum depth of cut of 3.40 mm and a full-radius corner profile with a 2.02 mm corner radius. The GMN chip breaker geometry promotes controlled chip evacuation at moderate to high feed rates. This insert is appropriate for machinists and toolroom professionals running production or precision turning applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for groovng applications in both production and job-shop environments. It fits the Series A4 toolholding system and is indexed with an insert seat size of 4. Typical applications include external relief grooves, undercuts, and parting-assist operations on ferrous and non-ferrous materials. The neutral hand orientation makes it compatible with both left- and right-hand toolholder configurations. The KCU10 grade and AlTiN coating make this insert well-matched to interrupted cuts and applications where heat generation is a concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD AlTiN coating for thermal and wear resistance\u003c\/li\u003e\n\u003cli\u003e4.05 mm cutting width with a maximum depth of cut of 3.40 mm\u003c\/li\u003e\n\u003cli\u003eFull-radius corner profile — corner radius 2.02 mm\u003c\/li\u003e\n\u003cli\u003eGMN chip breaker geometry for reliable chip control\u003c\/li\u003e\n\u003cli\u003eNeutral hand — compatible with left- and right-hand toolholders\u003c\/li\u003e\n\u003cli\u003eMulti-use rated; Series A4 system, insert seat size 4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Series A4 grooving toolholders accepting insert seat size 4, per the manufacturers catalog number A4R0405M04U00GMN.

Use a torque wrench appropriate for insert clamping screws and follow the toolholder manufacturers seating torque guidelines — do not overtighten, as carbide inserts are brittle and will crack under excess clamp load. Inspect the insert pocket and clamping screw for damage or debris before seating the insert. Verify the insert is fully seated 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: R\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: 4.05 mm (0.1594 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\u003eCorner Radius\u003c\/strong\u003e: 2.02 mm (0.0797 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: 0.7913 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0405\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: A4\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 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: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 4034818\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734671229234,"sku":"4034818","price":522.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ea36541a768f36c1f1d42ffada4b8a9.jpg?v=1788764636","url":"https:\/\/voomisupply.com\/products\/kennametal-4034818-grooving-insert-r0405gmn-kcu10-series-a4","provider":"Voomi Supply","version":"1.0","type":"link"}
