Iscar 5507428 Indexable Drill Insert SOMT09DT IC1008

Product Description

The ISCAR 5507428 is a square-shaped indexable drill insert designed for use in DR-TWIST series indexable drills. It carries the SOMT insert style with an IC1008 manufacturer grade and features a PVD-coated solid carbide construction. The inscribed circle measures 9.00 mm (0.3543 inches), the thickness is 0.1500 inches, and the corner radius is 0.60 mm (0.0236 inches). The IC1008 carbide grade is suited for a wide range of workpiece materials, making this insert a versatile choice for production drilling applications. Licensed machinists and CNC tooling technicians are the typical installers of this insert type.

This insert fits into indexable drilling toolholders that accept the SOMT 09T306 insert seat geometry. It is rated for use across universal workpiece material categories, including ISO material groups H, K, M, N, P, and S. Typical applications include through-hole and blind-hole drilling on machining centers and CNC lathes in both job-shop and production environments. The DT chipbreaker geometry is designed to manage chip evacuation during drilling operations.
