Sumitomo 19PWCGQ Turning Insert DNMG431EEF AC630M Carbide

Product Description

The SUMITOMO 19PWCGQ is a solid carbide turning insert in the DNMG431EEF geometry, manufactured to ANSI and ISO 13399 standards under Sumitomo grade AC630M. The insert features a CVD-applied aluminum oxide (Al2O3) coating designed to improve wear resistance and thermal stability during interrupted and continuous turning operations. It carries a 55-degree diamond shape (Insert Shape Code D), a neutral rake and hand orientation, and an EEF chip breaker. With an inscribed circle of 0.5 inches and a corner radius of 0.0156 inches, this insert suits finish to semi-finish turning applications where tight tolerances and controlled chip formation are required. Installation is performed by licensed machining professionals on CNC or manual lathes.

The 19PWCGQ is suited for turning operations on steel and stainless steel workpieces, with stainless steel designated as the secondary workpiece material (ISO material code M). The EEF chip breaker geometry promotes efficient chip control at moderate feed rates, making this insert appropriate for finish-turning passes on components requiring consistent surface finish. It fits toolholders designed for DNMG-style inserts held by clamp and pin method, common in both production and job-shop turning environments.

Key Features

• AC630M grade with CVD Al2O3 coating for enhanced thermal and abrasion resistance
• 55-degree diamond insert shape (ANSI code DNMG431EEF, ISO code DNMG150404N-EF)
• EEF chip breaker for controlled chip formation in finish to semi-finish turning
• Neutral rake and hand orientation for flexible toolholder compatibility
• Clamp and pin holding method for positive, repeatable insert seating
• Meets ANSI and ISO 13399 standards for insert geometry and identification

Compatibility

Designed for use in DNMG-style turning toolholders that accept clamp and pin insert retention. Compatible with toolholder systems specifying DNMG431 insert geometry. Suitable for steel and stainless steel (ISO material group M) turning applications.

Installation Notes

Installation should be performed by qualified machinists or toolroom personnel following the machine tool manufacturer's toolholder torque and clamping procedures. Power down and lock out the machine before indexing or replacing inserts. Inspect the toolholder pocket and locating pin for wear or debris before seating a new insert. Do not exceed the insert manufacturer's recommended feed and speed parameters for the AC630M grade.
