Seco 02506629 WCMX03 T400D Carbide Drill Insert 0.219 Ic

Product Description

The SECO 02506629 is a WCMX-style indexable drill insert designed for use in indexable insert drills across a wide range of workpiece materials. The insert features a solid carbide substrate with a PVD-applied TiAlN and TiN coating stack that provides wear resistance and thermal stability during interrupted or continuous drilling operations. The inscribed circle measures 0.219 inches, insert thickness is 0.094 inches, and the corner radius is 0.031 inches. The 80-degree trigon geometry supports the WCMX03 form factor. This insert is installed and replaced by machinists and tool crib personnel maintaining CNC or manual drill tooling setups.

The 02506629 insert is rated for universal primary workpiece material compatibility, covering material codes H, K, M, N, P, and S. This spans cast iron, non-ferrous alloys, steel, stainless steel, and superalloys, making it a broadly applicable choice for job shops and production environments running varied material schedules. It is sized as an 03 insert and fits toolholders and drill bodies that accept the WCMX03 seat configuration. The 7-degree relief angle supports free cutting action in through-hole and blind-hole drilling applications.

Compatibility

Designed for use in indexable drill toolholders and drill bodies that accept the WCMX03 insert seat configuration. Compatible with workpiece materials spanning cast iron, non-ferrous alloys, steel, stainless steel, and superalloys as indicated by material codes H, K, M, N, P, and S.

Installation Notes

Insert replacement is performed by machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Clean the insert pocket seat of chips and debris before seating the new insert, and torque the clamping screw to the drill body manufacturer's specified value using the appropriate Torx or hex key. Inspect the seating surface for wear or damage that could affect insert position and hole accuracy.
