It carries a KCU25 grade designation with a PVD-applied AlTiN coating that supports elevated cutting temperatures and extended tool life in steel and alloy applications. The insert features a left-hand orientation, a 3.18 mm cutting width, and a maximum depth of cut of 6.35 mm. A 12-degree rake angle and K-style chip breaker geometry promote controlled chip evacuation during interrupted and continuous grooving cuts. Machinists and tooling setup technicians install this insert into compatible Top Notch clamp-style toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for grooving operations in production turning environments, including general-purpose machining of steel, cast iron, and similar workpiece materials where a left-hand cutting geometry is required. The NFD insert style with a 55-degree included angle and a 0.19 mm corner radius (0.0075 inches) makes it appropriate for applications requiring a defined groove profile with controlled corner geometry. It is sold individually with a minimum order quantity of 5 units per transaction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCU25 solid carbide grade with PVD AlTiN coating for wear resistance and thermal stability\u003c\/li\u003e\n  \u003cli\u003e3.18 mm cutting width (0.1252 inches) for consistent groove sizing\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut 6.35 mm (0.2500 inches); effective range 5.00 to 10.00 mm\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cutting orientation for specific toolholder configurations\u003c\/li\u003e\n  \u003cli\u003eK-style chip breaker with 12-degree rake angle for controlled chip flow\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method compatible with Top Notch series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series clamp-style grooving toolholders that accept the NFD3125K insert style.
