Sumitomo 19RJ486 Turning Insert TPMR322ENF AC820P Carbide

Product Description

The SUMITOMO 19RJ486 is a solid carbide coated turning insert in the TPMR series, designed for precision external turning operations on CNC and manual lathes. This TPMR322ENF-geometry insert features a 60-degree triangular shape with a neutral hand orientation, a 3/8-inch inscribed circle, and a 1/32-inch corner radius. The AC820P grade coating is applied via CVD process, targeting steel workpiece materials across a broad range of cutting conditions. It is installed and replaced by machinists and CNC operators in production and job-shop environments. The ENF chip breaker geometry supports positive rake cutting action, helping manage chip formation during steel turning.

This insert is suited for turning steel components in both roughing and finishing applications where a triangular insert geometry and positive rake are appropriate. The TPMR style uses a clamp-type holding method. It conforms to ANSI code TPMR322ENF and ISO code TPMR160308N-SF, making it a direct fit for toolholders specced to either standard. Material grade designations C5A, C6, C7, and C8 indicate suitability across a range of steel-cutting speed and feed conditions.

Key Features

• Solid carbide substrate with CVD coating in AC820P grade for steel turning
• 60-degree triangle insert shape (ANSI code TPMR322ENF, ISO code TPMR160308N-SF)
• ENF chip breaker with positive rake for controlled chip formation
• 3/8-inch inscribed circle and 1/32-inch corner radius for precise geometry
• Clamp-type holding method compatible with standard TPMR toolholders
• Neutral hand orientation for flexible application in standard setups

Compatibility

Designed for use in TPMR-style clamp-type toolholders specced to ANSI TPMR322ENF or ISO TPMR160308N-SF insert geometry. Primary workpiece material is steel (material code P). Compatible with toolholders accepting material grades C5A, C6, C7, and C8 inserts.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the spindle before changing inserts. Seat the insert fully against the toolholder pocket and verify the clamp is secured before resuming cutting. Inspect the insert seat and clamp for wear or debris before each insert change to maintain accurate positioning.
