Iscar 5507881 SOMX07DT IC808 Indexable Drill Insert

Product Description

The ISCAR 5507881 is a solid carbide indexable drill insert in the SOMX style, designed for use in DR-TWIST series indexable drilling systems. Ground to a square shape with a 90-degree included angle, this insert carries the IC808 manufacturer grade and is PVD coated for extended wear resistance across a broad range of workpiece materials. The inscribed circle measures 0.3031 inches (7.70 mm), thickness is 0.1417 inches, and the corner radius is 0.0197 inches (0.50 mm). The DT chipbreaker geometry promotes reliable chip evacuation during drilling operations. Licensed machinists, tool-and-die technicians, and CNC operators are the primary users of this insert.

This insert is suited for use in indexable drill bodies that accept SOMX-style inserts within the DR-TWIST platform. It is rated for universal workpiece material compatibility, covering material grade range P15-P30 and ISO material codes H, K, M, P, and S. Typical applications include through-hole and blind-hole drilling in steel, stainless steel, cast iron, non-ferrous alloys, and heat-resistant superalloys in both production and job-shop environments. The insert conforms to ISO 13399 standards for cutting tool data representation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC technician with the machine fully stopped and locked out per applicable safety procedures. Use the correct torx or hex key as specified by the drill body manufacturer when seating the insert to avoid over-torquing the clamping screw. Inspect the insert pocket and clamping components for wear or debris before seating a new insert. Do not mix insert grades or styles within the same drill body unless confirmed compatible by the tooling system manufacturer.
