Running the G0400GMP chip breaker geometry with a KCU10 grade and a PVD-applied AlTiN coating, this insert delivers controlled chip evacuation and thermal resistance in demanding interrupted or continuous cut conditions. It carries a neutral hand orientation and a positive rake angle, making it well-suited for general-purpose grooving in both ferrous and nonferrous materials rated at material grades C3 and C4. Machinists and toolroom technicians are the primary installers of this insert type.\u003c\/p\u003e\u003cp\u003eThis insert is intended for grooving applications requiring a 4 mm cutting width and a maximum depth of cut of 3.51 mm, covering the typical depth-of-cut range of 3 mm to 4 mm. The 90-degree included angle and 0.41 mm corner radius suit standard groove profiles where a full radius is not required. Its compact 0.7874-inch overall length and 4.75 mm cutting height fit the A4-series insert seat size 4 toolholders. The multi-use designation means the insert can be applied across a variety of grooving scenarios, including face grooving and OD grooving on production turning equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU10 grade solid carbide with PVD AlTiN coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eGMP chip breaker geometry for positive rake and reliable chip control\u003c\/li\u003e\n\u003cli\u003e4 mm cutting width with a maximum depth of cut of 3.51 mm\u003c\/li\u003e\n\u003cli\u003e0.41 mm corner radius and 90-degree included angle for standard groove profiles\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard A4-series toolholders\u003c\/li\u003e\n\u003cli\u003eMulti-use rated for OD and face grooving on CNC turning centers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with A4-series insert seat size 4 toolholders.

Inspect the insert pocket and clamping screw for wear or debris before seating the new insert. Apply only the clamping torque specified by the toolholder manufacturer for the insert seat size. Do not use damaged or chipped inserts, as carbide inserts can fracture under interrupted-cut conditions if improperly seated.\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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\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\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\u003eCutting Width\u003c\/strong\u003e: 4 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 mm to 4 mm (0.1000 to 0.1500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.41 mm (0.0157 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: 0.7874 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 Seat Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0400\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\u003eMulti-use Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturers Catalog Number\u003c\/strong\u003e: A4G0400M04P04GMP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.011 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: 4034778\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":52037700583730,"sku":"4034778","price":608.97,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/142ab231f8a5842fefe6662c2907e504.jpg?v=1790024804","url":"https:\/\/voomisupply.com\/products\/kennametal-4034778-grooving-insert-kcu10-4mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
