Sumitomo 14HD919 Milling Insert SOMT120408PDERG ACK300

Product Description

The SUMITOMO 14HD919 is a solid carbide milling insert in the SOMT style, designed for high-performance face and shoulder milling operations. Manufactured to ISO standards, this insert carries the ACK300 grade designation and uses a PVD coating process to extend tool life in demanding cutting environments. The square insert shape measures 0.5000 inches in length, 0.5000 inches in width, and 0.1874 inches in thickness, with a corner radius of 0.0315 inches (0.80 mm). The G-style chip breaker promotes efficient chip evacuation during cuts. This insert is intended for installation and use by experienced machinists and tooling technicians.

The 14HD919 is optimized for machining cast iron workpieces, corresponding to ISO workpiece material code K. It is suited for use in face milling, shoulder milling, and high-feed milling applications in production and job-shop environments. The SOMT120408PDERG designation identifies the insert geometry, size code 1204, and chip breaker style, allowing direct cross-reference when selecting tooling for milling chucks and cutter bodies that accept this insert geometry. This insert is sold individually, with a minimum order quantity of 10 units.

Key Features

• ACK300 PVD-coated solid carbide grade for extended wear resistance in cast iron machining
• Square SOMT insert style with ISO-standard geometry for broad holder compatibility
• Corner radius of 0.0315 inches (0.80 mm) reduces edge chipping at entry and exit
• G-style chip breaker promotes controlled chip formation and evacuation
• Manufactured to ISO standards for consistent dimensional accuracy
• Lightweight at 0.015 pounds per insert, minimizing tooling imbalance at speed

Compatibility

Designed as an OEM-style replacement or direct-use insert for milling cutter bodies and toolholders that accept SOMT120408 geometry inserts per ISO standards.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the milling cutter body is removed from the spindle and all machine power is off before seating or replacing inserts. Use the correct torx or hex key as specified by the cutter body manufacturer when torquing insert screws — do not over-tighten, as solid carbide inserts are brittle. Inspect the insert pocket and seating surfaces for debris or damage before installing a new insert.
