Sumitomo 19T4APS Turning Insert VNMG332ESU AC8015P Carbide

Product Description

The SUMITOMO 19T4APS is a solid carbide turning insert designed for precision metal cutting operations on CNC lathes and turning centers. It carries the VNMG332ESU geometry with an AC8015P grade, featuring an Absotech Platinum CVD coating engineered for extended tool life on steel workpieces. The insert has a 35-degree diamond shape with a negative rake angle of 13 degrees, a 3/8-inch inscribed circle, a 1/32-inch corner radius, and an overall length of 0.6535 inches. Insert thickness measures 3/16 inch (0.1875 inches). The ESU chip breaker geometry supports stable chip control across a range of depths of cut and feed rates. Licensed machinists and CNC operators install this insert in compatible toolholders for finishing and semi-finishing passes on steel components.

This insert is rated for use on steel workpieces and is classified under ISO material grades P10 and P20. It is suited to both light finishing and moderate semi-finishing turning applications where consistent surface finish and dimensional control are required. The neutral hand orientation allows the insert to be used in standard right-hand toolholders. The pin and screw holding method ensures secure clamping during interrupted and continuous cuts. The insert conforms to ANSI and ISO 13399 standards, making it compatible with toolholder systems designed around those specifications.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench for the clamping screw as specified by the toolholder manufacturer. Inspect the toolholder seat and clamping components for wear or debris before seating a new insert.
