Sumitomo 192RCAW Turning Insert WNMG432EGZ AC415K Carbide

Product Description

The SUMITOMO 192RCAW is a solid carbide CVD-coated turning insert carrying the ANSI designation WNMG432EGZ and the ISO designation WNMG080408N-GZ. It is manufactured in grade AC415K with a proprietary FF coating and EGZ chip breaker geometry. The insert features an 80-degree trigon shape with a neutral hand and a 0-degree relief angle. With a 0.5-inch inscribed circle, a 0.0313-inch corner radius, and an insert thickness of 0.1875 inches, this insert is suited to precision external turning operations. It weighs approximately 0.026 pounds and is held using a clamp-and-pin method. Machinists and CNC operators install this insert in compatible toolholders during production turning of ferrous and cast iron workpieces.

This insert is designed for external turning applications in general machining and production environments. Its secondary workpiece material designation K indicates suitability for cast iron. The EGZ chip breaker is engineered to manage chip flow during moderate to finishing-depth cuts. The CVD coating on the AC415K carbide grade provides wear resistance appropriate for continuous and semi-interrupted cuts on cast iron and similar materials. This insert is used in CNC lathes and turning centers in light manufacturing, job shop, and production machining settings. It is sold individually with a minimum order quantity of 10 units.

• Secondary workpiece material code K indicating suitability for cast iron

Compatibility

Designed for use in toolholders accepting WNMG-style inserts. ANSI code WNMG432EGZ and ISO code WNMG080408N-GZ can be used to identify compatible toolholder systems. No additional model-specific compatibility data was provided in the product input.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. The machine spindle must be fully stopped and the turret indexed to a safe position before changing inserts. Seat the insert firmly against the pocket locating surfaces before tightening the clamp to ensure correct seating and prevent insert movement during cutting. Inspect the insert pocket and clamp pin for wear or debris prior to installation to avoid premature edge failure.
