Manufactured to Series A4 specifications, it features a 4.00 mm cutting width and a maximum depth of cut of 3.51 mm, making it well suited for medium-depth groove profiles in both ferrous and non-ferrous materials. The insert carries a KCU10 grade designation with a PVD-applied AlTiN coating, which supports elevated cutting speeds and improves wear resistance. The GMP chip breaker geometry delivers a positive rake angle to promote clean chip evacuation and reduce cutting forces during grooving cycles.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in metalworking applications requiring consistent, repeatable groove geometry. It fits Series A4 grooving toolholders and is appropriate for production turning environments in job shops, aerospace, automotive, and general machining facilities. The neutral hand orientation allows straightforward setup on standard turret positions. The 0.20 mm corner radius (approximately 0.0079 inches) and 4.75 mm cutting height contribute to stable engagement and predictable tool life across moderate material removal applications. Machinists and CNC programmers working in metric-measurement environments will find the insert sizing and specification directly applicable to common grooving routines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4.00 mm cutting width with a maximum depth of cut of 3.51 mm\u003c\/li\u003e\n\u003cli\u003eKCU10 solid carbide grade, Material Grade C3\/C4, with PVD-applied AlTiN coating for wear resistance\u003c\/li\u003e\n\u003cli\u003eGMP chip breaker with positive rake geometry for efficient chip control\u003c\/li\u003e\n\u003cli\u003eSeries A4 insert, Insert Size 0400, compatible with A4 grooving toolholder systems\u003c\/li\u003e\n\u003cli\u003e0.20 mm corner radius for controlled groove profile accuracy\u003c\/li\u003e\n\u003cli\u003eMulti-use tool designation supports use across varied grooving applications\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 in a safe, indexed position before seating or removing the insert. Use the appropriate torx or hex key as specified by the toolholder manufacturer when securing the insert clamp or screw — do not over-torque the clamping screw. Verify insert seating and clearance before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 4.00 mm (0.1575 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\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\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 Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\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\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\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: GMP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0400\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 4\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\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: 0.011 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: 4034777\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728511992114,"sku":"4034777","price":606.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f01f6eab3433e677f0e8dd0b808b8dbc.jpg?v=1788692454","url":"https:\/\/voomisupply.com\/products\/kennametal-4034777-grooving-insert-4mm-kcu10-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
