Sandvik Coromant 5756172 Indexable Drill Insert WCMX53

Product Description

The SANDVIK COROMANT 5756172 is a solid carbide indexable drill insert designed for use in indexable insert drills in metal-cutting operations. This insert carries the WCMX53 style designation, features a trigon (W) shape with a 7-degree relief angle, and is finished with a Titanium Nitride (TiN) coating applied via PVD process. The inscribed circle measures 0.3125 inches (7.94 mm), thickness is 0.125 inches, and the corner radius is 0.80 mm (0.0315 inches). Chipbreaker designation is 53, and the manufacturer grade is 1020. These inserts are installed by machinists and tooling technicians in CNC and manual drilling applications across production and job-shop environments.

This insert is intended for use in compatible SANDVIK COROMANT indexable drill bodies that accept WCMX-style inserts at insert size 5. Typical applications include through-hole and blind-hole drilling in ferrous and non-ferrous metals. The TiN coating provides surface hardness and wear resistance suited to general-purpose drilling at moderate cutting parameters. The insert is sold individually per package with a minimum order quantity of 10 units.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before replacing inserts. Use the correct torx or hex key as specified by the drill body manufacturer to seat and torque the insert clamp screw — do not overtighten or substitute fasteners. Inspect the insert pocket and clamping components for wear or debris before seating the new insert.
