Seco 02807379 Indexable Drill Insert Wcmx DP3000 Carbide

Product Description

The SECO 02807379 is an indexable drill insert designed for use in WCMX-style indexable drill bodies. Manufactured from solid carbide with a Duratomic coating process, this insert carries the DP3000 grade designation and features an 80-degree trigon (trigon) shape with a 7-degree relief angle. The inscribed circle measures 0.219 inches, the thickness is 0.094 inches, and the corner radius is 0.031 inches. It is intended for professional machining applications and is installed by machinists and tooling technicians working with CNC or manual drilling systems requiring replaceable cutting inserts.

This insert is suited for a wide range of workpiece materials. The DP3000 grade with Duratomic coating covers universal primary workpiece material categories including cast iron, non-ferrous materials, stainless steel, general steel, and heat-resistant superalloys, corresponding to ISO material groups H, K, M, N, P, and S. It is a common replacement insert for production drilling operations in metalworking environments, including both job shop and high-volume manufacturing settings.
