Sumitomo 14HB321 ACP300 Solid Carbide Milling Insert

Product Description

The SUMITOMO 14HB321 is a solid carbide milling insert designed for metal-cutting operations in milling applications. It carries the ACP300 manufacturer grade and features a PVD-applied coating for wear resistance during steel cutting. The insert has a parallelogram shape with an 85-degree included angle, a right-hand cutting orientation, and an 11-degree relief angle. Thickness measures 0.219 inches and width measures 0.402 inches, with a cutting edge effective length of 0.689 inches. The corner radius is 0.079 inches. Machinists and CNC tool setters install this insert in compatible milling cutter bodies as a direct replaceable cutting element.

This insert is suited for milling steel workpieces in both production and job-shop environments. The insert style is AXMT with an insert size code of 1235 and an ISO size designation of 170520. It is compatible with the WEX3000 cutter series and uses a G-style chip breaker geometry. Maximum depth of cut is 0.551 inches (14.00 mm), making it appropriate for moderate to aggressive face and shoulder milling passes on steel material with Primary Workpiece Material Code P classification.
