Iscar 5506338 SOMX05GF IC908 Indexable Drill Insert Square

Product Description

The ISCAR 5506338 is a square-style indexable drill insert designed for use in ISCAR DR-TWIST series indexable drills. It carries the SOMX05GF geometry with an IC908 carbide grade and a PVD-applied TiAlN coating for extended tool life in demanding drilling applications. The insert features a 5.4 mm inscribed circle, a 0.0157-inch (0.4 mm) corner radius, and a thickness of 0.0945 inches. The IC908 grade is engineered for universal workpiece material compatibility, making this insert a versatile choice for production drilling across a wide range of materials. Installation and changeover are performed by qualified machinists or tooling technicians.

This insert is suited for use in CNC machining centers, turning centers with live tooling, and dedicated drilling machines where the DR-TWIST modular drill body is in service. It is intended for drilling into ferrous and non-ferrous metals, stainless steels, superalloys, and cast materials, as indicated by its material grade classifications C1, C2, C6, and C7 and primary workpiece material codes H, K, M, P, and S. The GF chipbreaker geometry supports chip control in through-hole and blind-hole drilling operations across production environments.

Compatibility

Designed for use with ISCAR DR-TWIST series indexable drill bodies accepting SOMX insert style in size code 05. Confirm pocket geometry and clamping screw specification against the DR-TWIST body documentation before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the machine powered down and all axes locked out per facility lockout/tagout procedures. Use the correct torque screwdriver specified by ISCAR for the clamping screw to avoid seat damage or insert fracture. Inspect the insert pocket and clamping screw for wear or contamination before seating the new insert. Never force an insert into a damaged or improperly cleaned pocket.
