Sumitomo 19JQ827 Turning Insert WNMG433EGUW AC810P Carbide

Product Description

The SUMITOMO 19JQ827 is a solid carbide turning insert in the WNMG433EGUW geometry, manufactured to ANSI and ISO 13399 standards and offered in the AC810P grade. The insert features an 80-degree trigon shape with a neutral rake and neutral hand orientation, making it suitable for a wide range of turning operations. An Al2O3 (aluminum oxide) CVD coating provides thermal resistance and wear protection during cutting. The EGUW chip breaker geometry is designed for controlled chip formation. This insert is installed by machinists and CNC lathe operators in precision turning applications where consistent tool life and chip control are required.

The 19JQ827 is suited for turning operations on steel workpieces, classified under secondary workpiece material code P. It fits into standard WNMG-style toolholders that accept a 1/2-inch inscribed circle insert with clamp and pin holding methods. Typical applications include finish to semi-finish turning in production and job-shop environments on CNC lathes and manual turning centers. The neutral insert hand accommodates both right-hand and left-hand toolholder configurations.

Key Features

• AC810P grade solid carbide with CVD-applied Al2O3 coating for elevated-temperature wear resistance
• WNMG433EGUW geometry — 80-degree trigon shape with EGUW chip breaker for controlled chip evacuation
• Neutral rake and neutral hand — compatible with right-hand and left-hand WNMG toolholders
• 3/64-inch (0.0469 inch) corner radius for a balance of edge strength and surface finish
• Clamp and pin holding method for secure seating in the toolholder pocket
• Conforms to ANSI and ISO 13399 standards; ISO code WNMG080412N-GUW

Compatibility

Designed for use in standard WNMG-style toolholders accepting a 1/2-inch inscribed circle insert with clamp and pin holding. Primary application is steel turning (material code P). Confirm toolholder pocket tolerance and insert seat condition before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench for the clamp screw to avoid cracking the carbide substrate — refer to the toolholder manufacturer's specified torque value. Inspect the toolholder seat and locating pin for wear or debris before seating the new insert.
