Sumitomo 14HD320 Milling Insert ACK300 Solid Carbide

Product Description

The SUMITOMO 14HD320 is a solid carbide coated milling insert designed for high-productivity face and shoulder milling operations. Manufactured to the ACK300 grade with a PVD coating process, this insert delivers wear resistance and edge stability when cutting cast iron workpieces. The parallelogram insert shape (AXMT style) features an 85-degree included angle and an 11-degree relief angle, supporting a maximum depth of cut of 0.551 inches. At 0.138 inches thick and with a cutting edge effective length of 0.689 inches, this insert is sized for precision stock removal in demanding machining environments. Installation is handled by machinists and tooling technicians as part of a cutter body setup.

This insert is intended for milling applications where cast iron is the primary workpiece material, corresponding to ISO material group K. The right-hand cutting configuration suits standard right-hand cutter body orientations. The G chip breaker geometry promotes controlled chip evacuation during moderate to aggressive feed rates. Typical use cases include face milling, shoulder milling, and profile milling on cast iron components in production or job shop environments. The ACK300 grade with PVD coating is suited to dry or semi-dry cutting conditions common in cast iron machining.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before seating or replacing inserts. Use the correct torque wrench and insert screw specified by the cutter body manufacturer — do not over-tighten the clamp screw. Inspect the insert pocket seat for debris or damage before placing the new insert to ensure proper seating and runout.
