Sumitomo 10HWAEZ Turning Insert VNGG331ESU AC520U Carbide

Product Description

The SUMITOMO 10HWAEZ is a solid carbide turning insert in the VNGG331ESU geometry, designed for precision CNC lathe and turning center operations. It features a 35-degree diamond shape (V) with a neutral hand orientation and a positive 13-degree rake angle. The insert is PVD-coated with a dual-layer TiAlN and AlCrN system under SUMITOMO proprietary Super ZX designation, delivering thermal resistance and edge durability at elevated cutting speeds. The ESU chip breaker geometry controls chip flow during finishing and semi-finishing passes. Qualified machinists and CNC tooling technicians select this insert for demanding cutting applications.

This insert is suited for turning stainless steel and superalloy workpiece materials, corresponding to ISO material codes M and S. The positive rake geometry and Super ZX PVD coating make it effective in applications where heat generation and work-hardening are primary concerns, such as austenitic stainless and nickel-base alloy components. It fits standard VN-series insert pockets using clamp and pin holding methods. The ESU chip breaker is optimized for light-to-moderate depths of cut in finishing-range operations on these difficult-to-machine materials.

Compatibility

Designed for use in VN-series insert pockets accepting VNGG-style inserts with clamp and pin holding. Primary workpiece material compatibility includes stainless steel (ISO code M) and superalloys (ISO code S).

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before seating or removing any insert. Verify the insert pocket and seating surface are clean and free of chips before clamping. Follow the toolholder manufacturer torque guidance for clamp screws to avoid insert fracture or pocket damage.
