Sumitomo 14HB924 Carbide Milling Insert ACP300 Snmt

Product Description

The SUMITOMO 14HB924 is a solid carbide milling insert in the SNMT style, designed for face and shoulder milling applications in metal cutting operations. It carries the ACP300 manufacturer grade and features a TiAlN/AlCrN PVD coating that provides thermal resistance and edge wear protection at elevated cutting speeds. The insert measures 0.5315 inches long by 0.5315 inches wide by 0.2717 inches thick, with a square shape and a maximum depth of cut of 0.24 inches. It is installed by machinists and CNC toolroom technicians working with indexable milling toolholders.

This insert is suited for milling stainless steel and carbon or alloy steel in both production and job-shop environments. The G chip breaker geometry is optimized for controlled chip formation during medium-duty cuts in these materials. Typical applications include face milling, shoulder milling, and pocket milling operations on machining centers and mill-turn equipment. The SNMT 13T6 size class fits toolholders compatible with the DGC cutter series from Sumitomo.

Key Features

• Solid carbide substrate with ACP300 grade designation for high-performance steel and stainless steel cutting
• TiAlN/AlCrN PVD coating for improved heat resistance and extended tool life at the cutting edge
• Square SNMT insert shape with G chip breaker for controlled chip evacuation
• Maximum depth of cut of 0.24 inches (6.10 mm) per pass
• 0.00-degree relief angle suited to negative-rake toolholder seats
• Compatible with DGC cutter series indexable milling bodies

Compatibility

Designed for use with Sumitomo DGC cutter series indexable milling toolholders. Insert size code 13T6 fits seats accepting inserts in the 0.5000 to 0.6000 inch length range and 0.2500 to 0.3500 inch thickness range. Confirm pocket geometry and seating angle on the toolholder before installation.

Installation Notes

Indexable milling inserts are installed by trained machinists or toolroom technicians. Before changing inserts, ensure the spindle is fully stopped and the machine is locked out per shop lockout/tagout procedures. Use the correct torque wrench and insert screw specified by the toolholder manufacturer — do not overtighten, as this can fracture the insert or damage the seat. Inspect the pocket seat for chips or debris before seating the new insert to ensure full, flat contact.
