It carries a KCU25 manufacturer grade and an AlTiN coating applied via PVD process, providing thermal and wear resistance suited to interrupted cuts and moderate-to-high cutting speeds. The insert features a 0.1421-inch cutting width, a maximum depth of cut of 0.1500 inches, and a neutral rake angle of 0 degrees. Right-hand orientation is standard for this configuration. Machinists and CNC operators in production and job-shop environments install this insert as part of a Top Notch toolholder system.\u003c\/p\u003e\u003cp\u003eThis insert is intended for grooving applications where tight width tolerances and controlled depth are required. The NG insert style with a 55-degree included angle and a 0.0125-inch corner radius suits groove profiles requiring a near-sharp corner with minimal radial relief. It is appropriate for use in steel and harder workpiece materials where the AlTiN PVD coating provides a meaningful advantage over uncoated or TiN-coated alternatives. The insert size designation is 3142, corresponding to Top Notch toolholder bodies designed for that seat geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU25 grade solid carbide construction with AlTiN PVD coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003e0.1421-inch cutting width with a maximum depth of cut of 0.1500 inches\u003c\/li\u003e\n\u003cli\u003eNeutral rake angle and 0-degree lead angle for stable, consistent groove geometry\u003c\/li\u003e\n\u003cli\u003e0.0125-inch corner radius for near-square groove profiles\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation; insert size 3142 for Top Notch system compatibility\u003c\/li\u003e\n\u003cli\u003e55-degree included angle supports controlled chip formation in grooving cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series toolholder bodies accepting the NG3142 insert seat.

Before seating the insert, power down the machine and confirm the turret or toolpost is locked. Use the appropriate Top Notch clamping screw and torque driver specified by the toolholder manufacturer for secure insert retention. Inspect the seat pocket for chips or debris before seating to avoid insert fracture or poor seating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU25\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: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.1421 inches (3.61 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 0.1500 to 0.2000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 0.3440 inches (8.74 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3142\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Decimal Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 4109827\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730016403762,"sku":"4109827","price":251.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cd87d43c1e86309229598158216b88b.jpg?v=1788710250","url":"https:\/\/voomisupply.com\/products\/kennametal-4109827-grooving-insert-ng3142-kcu25-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
