Sumitomo 19JQAPS Carbide Turning Insert VNMG332ESU AC810P

Product Description

The SUMITOMO 19JQAPS is a VNMG-style solid carbide turning insert carrying manufacturer grade AC810P and an Al2O3 (aluminum oxide) CVD coating. It features a 35-degree diamond shape with a neutral hand orientation and a positive 13-degree rake angle. The inscribed circle measures 3/8 inches (0.375 inches), the corner radius is 1/32 inches (0.0313 inches), and insert thickness is 3/16 inches (0.1875 inches). The ESU chip breaker geometry is designed to manage chip flow during turning operations. This insert is installed by machinists and CNC turning specialists working in production and job-shop environments.

The 19JQAPS is suited for external and internal turning applications where steel is the primary workpiece material (ISO material code P). The AC810P grade with CVD Al2O3 coating is appropriate for continuous and light interrupted cuts on steel at moderate to high cutting speeds. The neutral hand configuration allows use in standard right-hand or left-hand toolholders accepting VNMG-series inserts. It is held in the toolholder via clamp and pin retention, which is standard for VNMG insert pockets.

Key Features

• AC810P grade with CVD Al2O3 coating for wear resistance on steel workpieces
• 35-degree diamond (V) insert shape with ESU chip breaker geometry
• Positive rake angle of 13 degrees for reduced cutting forces
• Neutral hand — compatible with standard VNMG toolholder pockets
• Clamp and pin holding method for secure seating under load
• Meets ANSI and ISO 13399 standards; ISO code VNMG160408N-SU

Compatibility

Designed as a direct-fit replacement for VNMG332 (ANSI) or VNMG160408 (ISO) insert pockets with clamp-and-pin retention on CNC and manual turning centers. Compatible toolholders must accept a 0.150-inch hole diameter and VNMG geometry with clearance code N and tolerance code M.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine in a locked-out, zero-energy state before any insert change. Seat the insert fully into the pocket, verify the pin engages the hole, and secure the clamp to the toolholder manufacturer's specified procedure before resuming cutting. Inspect the insert pocket and clamp components for wear or debris before seating a new insert. Do not exceed the cutting parameters recommended by SUMITOMO for grade AC810P on the target workpiece material.
