It carries a manufacturer grade of K68 with a bright uncoated finish, making it well suited for machining cast iron, hardened steels, and abrasion-resistant materials where coating buildup would reduce edge sharpness. The insert features a 3.18 mm cutting width and a maximum depth of cut of 3.81 mm, with a positive rake angle of 5 degrees and a corner radius of 0.19 mm for clean groove geometry. It is a right-hand orientation insert. Machinists and tooling technicians install this insert into compatible Top Notch grooving toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is used in external grooving, profiling, and light parting applications on manual and CNC turning equipment. It is appropriate for both job shop and production environments where consistent groove width and depth control are required. The NGP insert style and 3125 insert size designation indicate compatibility with standard Top Notch series toolholders. The 55-degree included angle and 3-degree lead angle contribute to stable chip formation during groove entry. This insert is sold individually and carries a minimum order quantity of 5 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide K68 grade with bright uncoated finish for abrasion resistance\u003c\/li\u003e\n\u003cli\u003e3.18 mm cutting width with maximum depth of cut of 3.81 mm\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 5 degrees for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.19 mm for accurate groove bottom geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand orientation, NGP insert style, Top Notch series\u003c\/li\u003e\n\u003cli\u003e55-degree included angle and 3-degree lead angle for stable entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KENNAMETAL Top Notch series grooving toolholders that accept the NGP 3125 insert style in right-hand configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed and replaced by a machinist or tooling technician.
