Sumitomo 14HBW1G Milling Insert ACP300 Solid Carbide

Product Description

The SUMITOMO 14HBW1G is a solid carbide milling insert designed for high-performance material removal in CNC milling applications. It features a round insert shape (QPMT style) with a PVD coating applied over the ACP300 carbide grade substrate. The inscribed circle measures 0.5000 inches and the insert thickness is 0.1875 inches, allowing a maximum depth of cut of 0.2500 inches. The H chip breaker geometry supports controlled chip evacuation during aggressive cutting passes. This insert is installed by CNC machinists and tool-and-die professionals working with production milling equipment.

This insert is suited for milling stainless steel and carbon steel workpieces in both production and job-shop environments. The ACP300 grade with PVD coating is engineered for wear resistance and edge retention when cutting ferrous materials classified under ISO material groups M and P. It is compatible with the WRCX cutter series. The ANSI code for this insert is QPMT4312PPENH ACP300, and the insert size code is 4312. Typical applications include face milling, shoulder milling, and contour milling operations where round insert geometry is specified.

Installation Notes

Insert installation should be performed by a qualified machinist or tooling technician with the spindle fully stopped and the machine in a locked-out, tagged-out state per applicable safety procedures. Seat the insert fully into the pocket and confirm the chip breaker orientation before torquing the clamping screw. Inspect the insert seat for debris or damage prior to seating a new insert. Do not exceed the maximum depth of cut of 0.2500 inches specified for this insert geometry.
