Sumitomo 19HVAPR Turning Insert VNMG331ESU AC510U Carbide

Product Description

The SUMITOMO 19HVAPR is a solid carbide coated turning insert designed for precision metal cutting on CNC lathes and turning centers. Manufactured to ANSI code VNMG331ESU and ISO code VNMG160404N-SU, this insert features a 35-degree diamond shape with a neutral hand orientation and a positive 13-degree rake angle. The AC510U grade with ZX proprietary PVD coating is engineered for cutting superalloys, delivering edge stability and wear resistance under demanding conditions. The inscribed circle measures 0.375 inches, insert length is 0.6535 inches, and the corner radius is 0.0156 inches (1/64 inch). Machinists and CNC operators in aerospace, energy, and high-precision manufacturing environments install this insert.

This insert is suited for turning superalloy workpieces where edge integrity and thermal resistance are critical. The ESU chip breaker geometry supports controlled chip evacuation at the cutting face. The VN series design is compatible with standard VNMG-style toolholders using clamp and pin holding methods, making it a direct-fit option in existing turning setups. It is appropriate for both roughing and finishing passes on difficult-to-machine materials such as nickel-based and titanium alloys.

Key Features

• AC510U grade with ZX PVD coating for superalloy cutting performance
• 35-degree diamond insert shape (V) with neutral hand for flexible tool path use
• ESU chip breaker geometry for controlled chip flow
• Positive rake angle of 13 degrees reduces cutting forces
• Clamp and pin holding method for secure seating in VNMG toolholders
• Meets ANSI and ISO 13399 standards for consistent interchangeability

Compatibility

Designed for use in standard VNMG-style turning toolholders that accept clamp and pin insert retention. Compatible with setups targeting superalloy workpiece materials per secondary material code S.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer — do not over-tighten the clamp screw. Inspect the insert seat and clamp pocket for chips or debris before seating the new insert to ensure proper contact and runout.
