Built to the Top Notch series standard, this right-hand insert carries a KCU25 grade designation and an AlTiN finish applied via PVD coating process. It delivers a 4.78 mm cutting width and a maximum depth of cut of 3.81 mm, making it suitable for moderate-depth groove profiles in steel and alloy workpiece materials. The clamp-style holding method ensures secure seating in compatible Top Notch toolholders. Installation and use are handled by machinists and CNC operators in production and job-shop turning environments.\u003c\/p\u003e\u003cp\u003eThis insert is intended for grooving applications on turning centers where controlled width and depth tolerances are critical. The NF insert style with a 55-degree included angle and a 0.57 mm corner radius suits medium-duty grooving in ferrous and non-ferrous materials. The 12-degree rake angle promotes chip control and reduces cutting forces. The AlTiN PVD coating provides thermal resistance and extended tool life at elevated cutting speeds. The insert ships individually and carries a minimum order quantity of 5 units per order placement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU25 solid carbide grade with AlTiN PVD coating for thermal wear resistance\u003c\/li\u003e\n\u003cli\u003e4.78 mm cutting width with maximum depth of cut of 3.81 mm\u003c\/li\u003e\n\u003cli\u003eRight-hand orientation, NF insert style with 55-degree included angle\u003c\/li\u003e\n\u003cli\u003e0.57 mm corner radius for controlled groove profile geometry\u003c\/li\u003e\n\u003cli\u003e12-degree rake angle for improved chip flow and reduced cutting force\u003c\/li\u003e\n\u003cli\u003eClamp-style holding method compatible with Top Notch series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Top Notch series grooving insert compatible with clamp-style Top Notch toolholders accepting NF-style inserts.
