Walter 5016882 Turning Insert CNMG543-NR4WAM30 Carbide

Product Description

The WALTER 5016882 is a solid carbide turning insert with ANSI insert code CNMG543 and ISO code CNMG160612, designed for general-purpose metal cutting operations. It features an 80-degree diamond (rhombic) insert shape, a 5/8-inch inscribed circle, and a 3/64-inch corner radius (0.0469 inches). The WAM30 manufacturer grade and NR4 chip breaker geometry suit a range of cutting conditions. The insert uses a negative rake angle of 20 degrees with a chamfered and honed cutting edge style, delivering controlled chip flow and edge stability. Holding is accomplished via clamp and pin methods. This insert is installed by machinists and tool setters in CNC turning centers and manual lathes.

The 5016882 is suited for turning, facing, and boring operations on compatible toolholders designed for CNMG-style inserts. The negative side clearance and neutral hand orientation make it adaptable across a range of workpiece materials and part geometries. With four available cutting edges per insert, it supports efficient tooling economics in production environments. The NR4 chip breaker is matched to moderate depths of cut and feed rates typical in roughing to semi-finishing passes.

Installation Notes

Installation is performed by qualified machinists or tool setters. Power down and lock out the machine spindle before indexing or replacing inserts. Ensure the toolholder pocket and seating surfaces are clean and free of chips before seating the insert. Use the correct torque driver for the clamping screw to avoid insert rocking or premature failure.
