Sumitomo 19RJ111 TPMT332ESUA Carbide Turning Insert

Product Description

The SUMITOMO 19RJ111 is a solid carbide turning insert in the TPMT series, designed for precision external turning operations on steel workpieces. This triangular insert carries the AC820P manufacturer grade and features a CVD-applied aluminum oxide (Al2O3) coating that improves wear resistance and thermal stability at the cutting edge. The neutral hand orientation and positive rake angle of 8 degrees reduce cutting forces and help control chip flow. The insert is held in place by a screw-clamp method and is rated under ANSI and ISO 13399 standards. Licensed machinists and CNC lathe operators install this insert in tool holders designed for TPMT-style seating.

This insert is suited for finishing and semi-finishing passes on steel (ISO workpiece material code P) in both production shop and job shop environments. The ESU chip breaker geometry promotes controlled chip formation across a range of depths of cut and feed rates typical in steel turning applications. It is used in CNC turning centers and manual lathes wherever a screw-clamped, triangular carbide insert is specified for steel cutting.

Key Features

• AC820P grade carbide with CVD Al2O3 coating for extended tool life in steel turning
• ESU chip breaker geometry for controlled chip formation on steel workpieces
• Positive rake angle (8 degrees) reduces cutting forces and tool pressure
• Neutral hand insert fits standard TPMT-compatible right- and left-hand tool holders
• Screw-clamp insert holding method for secure, repeatable seating
• Compliant with ANSI and ISO 13399 standards

Compatibility

Designed as an OEM-style replacement for TPMT-series screw-clamp tool holders accepting a 3/8-inch inscribed circle triangular carbide insert. ISO code TPMT160408N-SU confirms fitment with ISO-standard TPMT tool holder pockets.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Confirm the machine spindle is fully stopped and all motion is locked out before indexing or replacing inserts. Use the correct torque driver or wrench for the clamping screw to avoid insert cracking or improper seating. Inspect the insert pocket for chips or debris before seating the new insert.
