The insert features a 2.00 mm cutting width and a maximum depth of cut of 1.70 mm, making it suited for fine, tight-tolerance groove profiles. Applied via a PVD process, the AlTiN coating provides thermal resistance and extended tool life in demanding cutting conditions. Machinists and toolroom technicians install this insert into compatible A4-series toolholders for high-precision turning work.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in metalworking applications where consistent groove geometry and repeatable insert indexing are critical. The full-radius profile with a 1.00 mm corner radius supports clean groove-bottom finishes. The neutral hand orientation makes it adaptable to a range of grooving configurations. It is suited for production turning environments handling steel, stainless steel, and similar materials where the KCU25 carbide grade and AlTiN coating perform effectively under moderate to high cutting speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with PVD-applied AlTiN coating for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003e2.00 mm cutting width with a maximum depth of cut of 1.70 mm\u003c\/li\u003e\n  \u003cli\u003eFull-radius insert profile with 1.00 mm corner radius for smooth groove-bottom geometry\u003c\/li\u003e\n  \u003cli\u003eGMP chip breaker design for controlled chip formation in grooving operations\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible use in varied grooving setups\u003c\/li\u003e\n  \u003cli\u003eMulti-use tool designation supports use across compatible A4-series grooving systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in A4-series grooving toolholders.

Seat the insert fully into the toolholder pocket and torque the clamping screw per the toolholder manufacturer specifications. Inspect the insert seat and clamping surfaces for chips or debris before installation to ensure proper seating and accurate cutting geometry. Do not use a damaged or worn insert seat, as improper seating can affect groove accuracy and tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 2.00 mm (0.0787 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.70 mm (0.0670 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.00 mm (0.0394 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 2.08 mm (0.0820 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.7874 inches (approx. 20.0 mm)\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: KCU25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\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 Style\u003c\/strong\u003e: R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: Yes\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: 0200\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: 0.002 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 3871115\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731800064306,"sku":"3871115","price":592.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e4137163e31713aa40f0dc89b2338e2.jpg?v=1788735080","url":"https:\/\/voomisupply.com\/products\/kennametal-3871115-grooving-insert-r0200gmp-kcu25-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
