Sumitomo 19PWAPS VNMG-332 Turning Insert AC630M Carbide

Product Description

The SUMITOMO 19PWAPS is a VNMG-332 style indexable turning insert designed for precision metal-cutting operations on CNC lathes and turning centers. It is manufactured from solid carbide and features an Al2O3 (aluminum oxide) coating applied via CVD process, using the AC630M manufacturer grade. The insert carries a 35-degree diamond shape (V code), a neutral hand orientation, and an ESU chip breaker geometry with a positive rake angle of 13 degrees. A 0.0313-inch corner radius and ANSI code VNMG332ESU make this insert a standard, well-supported choice for shops running high-volume turning programs requiring consistent chip control and edge life.

This insert is suited for turning applications involving stainless steel as a secondary workpiece material (ISO material code M). The ESU chip breaker geometry is optimized for finishing and semi-finishing cuts where chip evacuation and surface finish are priorities. It installs in tool holders designed for VNMG-style inserts using clamp and pin holding methods, which are common on both OEM and aftermarket turning tool bodies. Shops running ISO or ANSI-compliant tooling systems will find this insert integrates without modification. The ISO code for this insert is VNMG160408N-SU.

Key Features

• Solid carbide construction with CVD-applied Al2O3 coating for thermal resistance and wear life
• AC630M grade rated for material grades C5, C5A, C6, and C7
• ESU chip breaker geometry supports positive rake cutting with controlled chip flow
• 35-degree diamond insert shape (V) with neutral hand — fits a wide range of VNMG holder configurations
• 0.0313-inch corner radius suitable for finishing and light semi-finishing passes
• Compliant with ANSI and ISO 13399 standards for tooling data interoperability

Compatibility

Designed for use in VNMG-style indexable turning tool holders that accept clamp and pin insert retention. Compatible with tooling systems referencing ANSI code VNMG332ESU or ISO code VNMG160408N-SU. Rated for material grades C5, C5A, C6, and C7, with stainless steel listed as a secondary workpiece material application.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and de-energize the machine tool before indexing or replacing inserts. Seat the insert fully against the tool holder pocket and confirm the clamp and pin retention are secure before resuming operation. Handle carbide inserts carefully — edges are brittle and can chip if dropped or impacted against hard surfaces.
