It carries the CNMG643RP industry standard designation and ISO code CNMG190612RP, with manufacturer grade KCP10B. The insert features a multilayer CVD coating system — TiCN, Al2O3, and TiOCN — that delivers high wear resistance on steel (P) and moderate wear resistance with toughness on aluminum and non-ferrous materials (N). With a 3\/4 inch inscribed circle, 1\/4 inch thickness, and a 3\/64 inch corner radius, this is a robust insert suited to roughing and medium machining operations. Licensed machinists and CNC lathe operators install it using a clamp or pin holding method.\u003c\/p\u003e\n\u003cp\u003eThis insert is applicable in turning, facing, and boring operations on CNC and manual lathes in both production and job-shop environments. Its RP chip breaker geometry is engineered for roughing and medium machining, making it well suited to interrupted or continuous cuts on steel and cast iron. The 80-degree diamond shape and negative rake angle provide strength at the cutting edge, while the chamfered and honed cutting edge style improves edge integrity under heavy loads. It is a multi-use insert with 4 indexable cutting edges, reducing per-edge tooling cost in high-volume turning applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCNMG643RP geometry with 80-degree diamond insert shape for strong cutting edge support\u003c\/li\u003e\n  \u003cli\u003eMultilayer CVD coating: TiCN, Al2O3, and TiOCN for high wear resistance on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eKCP10B grade optimized for steel (P) high wear resistance and non-ferrous (N) toughness\u003c\/li\u003e\n  \u003cli\u003eRP chip breaker for roughing and medium machining operations\u003c\/li\u003e\n  \u003cli\u003e4 indexable cutting edges with clamp or pin holding compatibility\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style for improved edge integrity under load\u003c\/li\u003e\n  \u003cli\u003eNegative rake and negative side clearance for maximum insert body strength\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for KENLOC series toolholders accepting CNMG643 inserts with clamp or pin holding.

Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully in the toolholder pocket and verify clamping torque per the toolholder manufacturer specification before resuming cuts. Inspect the cutting edge condition and chip breaker geometry before each use to confirm no chipping or wear beyond acceptable limits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG643\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG190612\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG643RP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG190612RP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP10B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80-Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN, Al2O3, TiOCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: MTCVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProprietary Coating Designation\u003c\/strong\u003e: Multilayer Coating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: RP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing, Medium Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered, Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 19.34 mm (0.7616 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inch (0.0469 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.3125 inches (7.93 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2536 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Size Code\u003c\/strong\u003e: 643\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Size Code\u003c\/strong\u003e: 190612\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: P, N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade Characteristics\u003c\/strong\u003e: Steel (P) - High Wear Resistance;
