Manufactured to the NG3189K form factor in the Top Notch series, it features a KC850 grade substrate with a CVD-applied multilayer coating of TiC, TiCN, and TiN for wear resistance and thermal stability. The insert is configured for left-hand cutting with a 4.80 mm cutting width and a maximum depth of cut of 3.81 mm. A positive rake angle of 10 degrees and a K-style chip breaker promote controlled chip evacuation in steel and cast iron applications. Machinists and CNC programmers working in production turning will find this insert suited to finishing and light roughing passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in external grooving, face grooving, and profiling operations on lathes equipped with Top Notch-style toolholders. The KC850 grade with CVD TiC, TiCN, and TiN coating targets steel, alloy steel, and cast iron workpiece materials classified under material grades C5 and C6. It is suited for medium to high cutting speeds in both dry and wet cutting environments. The left-hand orientation positions the insert for specific tool approach directions, so confirm toolholder hand before ordering. This insert is sold individually but carries a minimum order quantity of 5 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC850 solid carbide grade with CVD multilayer TiC, TiCN, and TiN coating for extended tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e4.80 mm cutting width with a maximum depth of cut of 3.81 mm\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 10 degrees reduces cutting forces and heat generation\u003c\/li\u003e\n  \u003cli\u003eK-style chip breaker geometry promotes reliable chip control during grooving\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.57 mm (0.0225 inches) for controlled groove floor geometry\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for directional toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eTop Notch series insert size 3189 for use in compatible Top Notch grooving toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENNAMETAL Top Notch series grooving toolholders that accept NG-style inserts at insert size 3189.
