Sumitomo 19RJWAW Turning Insert AC820P Carbide

Product Description

The SUMITOMO 19RJWAW is a TNMG-style turning insert designed for precision metal cutting on CNC lathes and turning centers. Built from solid carbide with a CVD coating in manufacturer grade AC820P, this triangular insert delivers consistent performance in general-purpose and interrupted turning operations. The insert features a 60-degree included angle, a 0.6496-inch length, a 3/8-inch inscribed circle, and a 1/32-inch corner radius. Its negative rake geometry and neutral hand orientation make it a versatile choice for a wide range of turning applications. Licensed machinists and CNC operators install this insert on toolholders that accept the TNMG form factor.

This insert is rated for use on primary workpiece materials categorized as P (steel) and M (stainless steel and similar alloys), making it applicable across automotive, general manufacturing, and industrial machining environments. The ENG chip breaker geometry is engineered to manage chip flow and reduce built-up edge during medium to finishing turning passes. It conforms to ANSI code TNMG322ENG and ISO code TNMG160308N-UG, allowing direct cross-reference to compatible toolholding systems used in standard production turning setups. Minimum order quantity is 10 inserts, sold individually per package.

Key Features

• AC820P CVD-coated solid carbide construction for extended tool life in steel and stainless cutting
• ENG chip breaker geometry for controlled chip formation during medium to finish turning
• Negative rake, neutral hand design compatible with standard TNMG toolholders
• 60-degree triangular insert shape provides three usable cutting edges per insert
• Dual ANSI and ISO 13399 compliance simplifies cross-referencing with existing tooling systems
• Clamp and pin holding method for secure, repeatable insert seating

Compatibility

Designed for use in toolholders configured for the TNMG insert style with clamp and pin holding. ANSI code TNMG322ENG and ISO code TNMG160308N-UG allow direct cross-reference to compatible toolholding systems. Rated for P and M workpiece material categories per ISO material classification.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before seating or replacing inserts. Verify that the toolholder pocket and clamping components are clean and free of debris before installing the insert. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer specification and inspect the seating surface for proper contact before resuming cuts.
