Built to the NG3125 insert style in the Top Notch series, this left-hand insert features a CVD-applied multilayer coating of TiC, TiCN, and TiN over a KC850 carbide substrate. The KC850 grade is suited for steel and cast iron applications requiring a tough, wear-resistant cutting edge. With a 3.18 mm cutting width and a maximum depth of cut of 3.81 mm, it is sized for medium grooving work where dimensional consistency and surface finish are critical. Licensed machinists and CNC tooling technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for grooving, parting, and profiling operations in metalworking environments. It carries a neutral rake geometry and a 55-degree included angle with a 0.19 mm corner radius, making it appropriate for machining steels and cast irons in material grades C5 and C6. It is suited to production turning environments where CVD-coated solid carbide tooling is specified for extended tool life and consistent chip control at moderate to high cutting speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with KC850 manufacturer grade for toughness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCVD multilayer coating: TiC, TiCN, and TiN for heat resistance and extended edge life\u003c\/li\u003e\n  \u003cli\u003e3.18 mm cutting width with a maximum depth of cut of 3.81 mm\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for specific toolholder configurations\u003c\/li\u003e\n  \u003cli\u003eNeutral rake geometry with 0.19 mm corner radius and 55-degree included angle\u003c\/li\u003e\n  \u003cli\u003eTop Notch series insert style NG3125 for secure toolholder seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Top Notch series toolholders that accept the NG3125 insert style.
