Sumitomo 19PWAFT Turning Insert WNMG432EMU AC630M Carbide

Product Description

The SUMITOMO 19PWAFT is a WNMG432EMU AC630M grade solid carbide turning insert designed for precision lathe and turning center operations. Featuring a CVD-applied aluminum oxide (Al2O3) coating, this insert delivers thermal resistance and wear protection during demanding cutting passes. The trigon (W) insert shape provides an 80-degree included angle and a neutral hand orientation, making it a versatile choice for general turning and profiling. At 0.3425 inches in length with a 0.5-inch inscribed circle and a 0.0313-inch corner radius, this insert fits standard WNMG toolholders and suits both roughing and finishing applications in steel and stainless steel.

This insert is intended for use in CNC lathes and manual turning centers across metalworking operations in industrial, toolroom, and production machining environments. The AC630M grade and EMU chip breaker geometry are suited for turning stainless steel and similar materials where controlled chip formation and edge integrity are critical. It is installed by machinists and toolroom technicians using standard clamp and pin insert-holding systems. The ISO code for this insert is WNMG080408N-MU, which aids cross-referencing with ISO 13399-compliant tooling systems.

Key Features

• EMU chip breaker geometry designed for controlled chip evacuation on stainless steel
• Neutral hand orientation supports flexible toolholder setups
• 80-degree trigon (W) shape with 0.0313-inch corner radius for profiling and general turning
• Complies with ANSI and ISO 13399 standards; ISO code WNMG080408N-MU
• Clamp and pin holding method compatible with standard WNMG insert pockets

Compatibility

Designed for use in WNMG-style insert pockets with clamp and pin holding systems. ISO code WNMG080408N-MU supports direct cross-referencing with ISO 13399-compliant toolholders. Rated for turning stainless steel (ISO material group M) and compatible secondary workpiece materials.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torque driver for the clamping screw per the toolholder manufacturer's specification — do not overtighten by hand. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert.
