Seco 74015899 Indexable Drill Insert WCMX0586 Hx Carbide

Product Description

The SECO 74015899 is a solid carbide indexable drill insert designed for use in indexable insert drills in metal-cutting operations. This insert carries the WCMX style designation with an HX manufacturer grade and features a Trigon (80-degree included angle) shape with a 7-degree relief angle. It is uncoated with a bright finish, making it well-suited for applications where coating is not required or where base carbide performance is preferred. The 0.8 mm corner radius provides controlled edge geometry for consistent chip formation. With a Material Grade of C2, this insert is intended for machining cast iron and nonferrous materials. Machinists and CNC operators in production and job-shop environments use this insert as a standard consumable replacement.

This insert is intended for use in short-hole drilling and boring operations on machining centers, CNC lathes, and drill presses equipped with compatible indexable insert drill bodies. It is suited for light-to-medium duty cutting applications in cast iron and nonferrous workpiece materials. The WCMX insert style is a widely used format in indexable drill tooling, making this a common replacement insert in shops running standard indexable drill programs. A licensed machinist or CNC operator should handle replacement and seating of the insert.

Installation Notes

Insert replacement should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before accessing the tool holder or drill body. Use the appropriate torx or hex key specified by the drill body manufacturer to seat and torque the insert clamp screw — do not overtighten. Inspect the pocket seating surface for chips or debris before installing a new insert to ensure proper seating and edge geometry.
