Iscar 5598816 Indexable Drill Insert SOMT09GF IC328

Product Description

The ISCAR 5598816 is a solid carbide indexable drill insert designed for use in ISCAR DR-TWIST series indexable drills. Carrying the SOMT insert style with the IC328 manufacturer grade, this square-shaped insert features a 9.00 mm (0.3543 inches) inscribed circle, a thickness of 0.1500 inches, and a 0.60 mm (0.0236 inches) corner radius with a GF chipbreaker geometry. The PVD coating process delivers a hard, wear-resistant surface layer suited to demanding cutting conditions. Licensed machinists and tooling technicians install these inserts as replaceable cutting edges in multi-insert drill bodies targeting through-hole and blind-hole drilling operations.

This insert is rated for universal primary workpiece material application, covering ISO material groups M (stainless steel), P (steel), and S (heat-resistant alloys), making it a versatile choice across job shop and production environments. It is sized at insert size code 09T306 and conforms to ISO 13399 standards for cutting tool data representation. Typical applications include drilling operations on CNC machining centers and turning centers where DR-TWIST style drill bodies are in use. The 90-degree included angle and square insert shape suit standard flat-bottomed and through-hole drilling profiles.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the machine powered down and all axes at rest. Use the correct torx or hex key specified by the drill body manufacturer to seat the insert at the proper clamping torque — do not overtighten or use impact tools. Inspect the insert pocket and clamping screw for wear or damage before installing a new insert. Always verify insert orientation and seating before resuming cutting operations.
