Sumitomo 19JQAWF DNMG432ESE AC810P Carbide Turning Insert

Product Description

The SUMITOMO 19JQAWF is a DNMG432ESE-style solid carbide turning insert with an AC810P grade and CVD-applied Al2O3 coating. It features a 0.5-inch inscribed circle, a 3/16-inch insert thickness, and a 1/32-inch corner radius. The 55-degree diamond shape (D) and neutral hand orientation make it a direct-fit option for external turning operations on CNC lathes. A positive rake angle of 13 degrees reduces cutting forces on the workpiece. The ESE chip breaker geometry is designed to manage chip flow during moderate-depth steel turning applications. Machinists and CNC operators install this insert as a standard indexable tip in compatible turning toolholders.

This insert is suited for turning operations where steel is the primary workpiece material, consistent with its P-grade secondary workpiece material code. It is intended for use in production CNC turning centers and manual lathes equipped with DNMG-style insert seats that use clamp and pin holding methods. The CVD Al2O3 coating provides wear resistance and thermal stability during continuous or interrupted cuts in steel. This insert is commonly used in job shops, production machining cells, and toolroom environments where consistent surface finish and insert life are priorities.

Compatibility

Designed as an OEM-style indexable replacement for DNMG-style turning toolholders using clamp and pin holding, with an ANSI code of DNMG432ESE and ISO code DNMG150408N-SE.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before indexing or replacing inserts, ensure the machine spindle is fully stopped and all motion has ceased. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when securing the insert. Inspect the insert pocket and seating surface for chips or debris before installation to ensure proper seating and runout.
