Iscar 5505233 Indexable Drill Insert SOMT12GF IC908

Product Description

The ISCAR 5505233 is a solid carbide indexable drill insert designed for use in ISCAR DR-TWIST series indexable drills. The insert carries the SOMT12GF geometry with an IC908 PVD-coated carbide grade, making it suitable for a wide range of metalcutting applications across multiple workpiece material categories. It features a square shape with a 90-degree included angle, a 0.5000-inch (12.70 mm) inscribed circle, a 0.1874-inch thickness, and a 0.80 mm corner radius. The GF chipbreaker geometry promotes controlled chip formation during drilling operations. This insert is installed by machinists and CNC operators in production and job shop environments.

This insert is intended for use in compatible ISCAR DR-TWIST series indexable drill bodies. It supports drilling in a broad range of workpiece materials, covering ISO material groups H, K, M, P, and S, which correspond to hardened steels, cast irons, stainless steels, carbon and alloy steels, and high-temperature alloys. The universal material grade designation makes it a practical choice for shops running mixed-material work. Typical applications include through-hole and blind-hole drilling on CNC machining centers and drill presses where indexable insert tooling is specified.

Compatibility

Designed for use in ISCAR DR-TWIST series indexable drill bodies that accept SOMT12 style inserts. Insert size code is 12, with a 0.2200-inch hole diameter. Verify drill body specification against insert size code 120408 before installation.

Installation Notes

Installation is performed by machinists using the appropriate Torx or hex key as specified by the drill body manufacturer. The drill body must be removed from the machine spindle and all motion stopped before indexing or replacing inserts. Seating surfaces on the drill body pocket should be cleaned of chips and debris before installing the new insert to ensure proper seating and accurate hole geometry. Follow the drill body manufacturer's clamping sequence and procedure.
