Sandvik Coromant 5756155 Indexable Drill Insert WCMX53

Product Description

The SANDVIK COROMANT 5756155 is a solid carbide indexable drill insert designed for use in indexable insert drills in metal cutting and machining operations. Manufactured to the WCMX insert style with a trigon shape and a 7-degree relief angle, this insert features a PVD-applied Titanium Nitride (TiN) coating for improved wear resistance and tool life. The inscribed circle measures 0.375 inches (9.53 mm), thickness is 0.1563 inches (5/32 inches), and the corner radius is 0.80 mm (0.0315 inches). Grade 1020 with chipbreaker designation 53 makes this insert suited to the demanding conditions of indexable drilling. Installed by machinists and tool-room technicians.

This insert fits indexable drill bodies requiring a WCMX-style insert seat. Typical applications include hole-making operations in steel, cast iron, and similar workpiece materials in both production and job-shop environments. The trigon geometry with the 53 chipbreaker promotes controlled chip evacuation during drilling. The insert size designation is 6, and the mounting hole diameter is 0.1457 inches (3.70 mm). Installations are found across CNC machining centers and manual drill presses wherever indexable insert drills are deployed.

Installation Notes

Installation is performed by a qualified machinist or tool-room technician. Ensure the machine spindle is fully stopped and all energy is locked out before changing inserts. Use the correct Torx or insert-clamping screw driver specified by the drill body manufacturer to secure the insert; do not overtighten. Inspect the insert pocket for debris or damage before seating a new insert to ensure proper support and alignment.
