Running the NV4 insert style in the Top Notch series, this right-hand insert features a 0.1181-inch cutting width and a maximum depth of cut of 0.201 inches. The physical vapor deposition (PVD) AlTiN coating provides thermal resistance and extended tool life across a range of workpiece materials. Machinists and toolroom technicians working with C2 and C6 material grades will find this insert suited to demanding interrupted cuts and finishing passes where edge consistency matters.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in Top Notch series grooving toolholders that accept size 4 insert seats. It is suited to external grooving applications in production turning environments, including general-purpose part machining, groove dimensioning, and profile work where a right-hand cut orientation is required. The 20-degree lead angle and 40-degree included angle support controlled chip flow and consistent groove geometry. A 0.0125-inch corner radius reduces stress concentration at groove shoulders. This insert does not feature a full radius geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePVD AlTiN coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e0.1181-inch cutting width for precise groove dimensioning\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.201 inches; rated range of 0.2000 to 0.3000 inches\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation with a 20-degree lead angle and 40-degree included angle\u003c\/li\u003e\n\u003cli\u003e0.0125-inch corner radius for reduced stress at groove edges\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding for positive location in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series toolholders accepting size 4 insert seats with an NV insert style.
