It carries a KCU25 manufacturer grade with an AlTiN coating applied via PVD process, providing strong wear resistance and thermal stability at the cutting edge. The insert features a 0.1252-inch cutting width, a maximum depth of cut of 0.25 inches, and a neutral rake angle with a 0.0075-inch corner radius. It belongs to the Top Notch series and is configured for right-hand cutting. Machinists and toolroom professionals use this insert for precision groove profiling in ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for use in industrial turning applications where controlled groove width and repeatable depth are critical. It fits toolholders designed for the Top Notch NGD insert style. The K chip breaker geometry supports chip control across a range of feed and depth conditions. Typical applications include grooving on steel, stainless, and similar workpiece materials in production and job-shop environments. The insert is sold individually but requires a minimum order quantity of 5 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with KCU25 grade for toughness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating via PVD process for thermal protection and extended tool life\u003c\/li\u003e\n  \u003cli\u003e0.1252-inch cutting width with maximum depth of cut of 0.25 inches\u003c\/li\u003e\n  \u003cli\u003eK chip breaker geometry for effective chip evacuation during grooving\u003c\/li\u003e\n  \u003cli\u003eNeutral rake angle and 55-degree included angle for stable cutting geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand configuration in the Top Notch NGD series for positive toolholder engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series toolholders accepting NGD-style inserts.
