Sumitomo 19RJWCV Turning Insert TPMT32.52ESU AC820P Carbide

Product Description

The SUMITOMO 19RJWCV is a solid carbide turning insert in the TPMT series, designed for precision external turning operations on steel workpieces. It carries the AC820P manufacturer grade with an aluminum oxide (Al2O3) CVD coating that improves wear resistance and thermal stability at the cutting edge. The 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. A positive rake angle of 8 degrees and the ESU chip breaker geometry help manage chip flow during continuous and interrupted steel cutting. This insert is installed by machinists and CNC operators working in production turning environments.

The 19RJWCV is suited for turning applications on steel, corresponding to ISO material group P. The TPMT-style insert seats with a screw-holding method and is compatible with tool holders that accept the TPMT insert style with a clearance code P and tolerance code M. Typical use cases include OD turning on lathes and turning centers in job shops and manufacturing facilities. The ESU chip breaker is optimized for general-purpose steel cutting at moderate feed rates and depths of cut.

Key Features

• AC820P grade with CVD-applied Al2O3 coating for thermal and wear resistance in steel cutting
• 60-degree triangular insert shape (ANSI code TPMT32.52ESU, ISO code TPMT16T308N-SU) provides multiple usable cutting edges
• ESU chip breaker geometry promotes controlled chip formation on steel workpieces
• Positive rake angle (8 degrees) reduces cutting forces and heat generation
• Screw-holding method ensures rigid, repeatable seating in compatible tool holders
• Neutral hand orientation allows use in standard right-hand and left-hand turning setups

Compatibility

Designed for use in TPMT-style screw-on turning insert holders that accept a 3/8-inch inscribed circle, clearance code P, tolerance code M insert. Primary workpiece material compatibility is steel (ISO material group P). Conforms to ANSI and ISO 13399 standards.

Installation Notes

Installation is performed by qualified machinists or CNC technicians. Power down and lock out the machine before seating or removing inserts. Use the appropriate torque driver for the insert-clamping screw to avoid cracking the carbide substrate or stripping the screw seat. Inspect the tool holder pocket and seating surfaces for chips or wear before installing a new insert.
