Sumitomo 14HDW16 QPMT4312PPEN ACK300 Carbide Milling Insert

Product Description

The SUMITOMO 14HDW16 is a solid carbide milling insert in QPMT style, sized to ANSI code QPMT4312PPEN with a manufacturer grade of ACK300. It features a dual-layer TiAlN/AlCrN coating applied via PVD process, providing wear resistance and thermal stability during interrupted and continuous milling operations. At 0.1875 inches thick with an inscribed circle of 0.5000 inches, this right-hand insert is engineered for consistent depth of cut up to 0.2500 inches. Machinists and tooling specialists install this insert in compatible milling cutter bodies for precision metal removal in production environments.

This insert is designed for primary use on cast iron workpieces, classified under workpiece material code K. The QPMT insert style and 4312 size designation target medium to high-feed face and shoulder milling applications. It is suited for use in CNC milling centers and conventional milling machines where controlled chip formation and flank wear resistance are critical. The PVD TiAlN/AlCrN coating maintains edge integrity across varying cutting speeds typical in cast iron machining.

Key Features

• Solid carbide construction with material grade C4 for rigidity and wear resistance
• PVD-applied TiAlN/AlCrN dual coating for thermal and abrasion resistance
• QPMT insert style, size code 4312, right-hand cutting geometry
• Relief angle of 11 degrees for positive clearance during cut
• Maximum depth of cut 0.2500 inches with inscribed circle of 0.5000 inches
• Meets ANSI standards; ANSI code QPMT4312PPEN ACK300

Compatibility

Compatible with the WRCX cutter series as specified by the manufacturer. Designed as an OEM-style replacement or direct-fit insert for milling cutter bodies accepting QPMT 4312-size inserts in right-hand orientation.

Installation Notes

Installation is performed by machinists or tooling technicians following standard insert-change procedures for indexable milling tools. Ensure the cutter body pocket is clean and free of chips or debris before seating the insert. Use the manufacturer-recommended torx or hex key to torque the insert screw to the cutter body specification — do not overtighten, as this can fracture the carbide substrate. Verify insert orientation and hand designation match the cutter body before resuming machine operation.
