Iscar 5504598 Indexable Drill Insert SOMT06DT IC328 Carbide

Product Description

The ISCAR 5504598 is a solid carbide indexable drill insert in the SOMT style, designed for use with DR-TWIST series indexable drilling systems. Manufactured in the IC328 grade with a PVD coating, this insert delivers wear resistance across a broad range of workpiece materials including steel, stainless steel, and non-ferrous alloys. The square insert shape features a 90-degree included angle and a 0.40 mm corner radius. With an inscribed circle diameter of 6.00 mm (0.2362 inches) and a thickness of 0.0772 inches, this insert is sized for precision drilling applications where consistent edge geometry and reliable chip control are required. The DT chipbreaker designation supports effective chip evacuation in deep-hole drilling operations.

This insert is intended for use in production drilling environments across metalworking applications including general machining, aerospace component work, and structural steel fabrication. The IC328 PVD-coated grade is rated for universal workpiece materials under material codes M, P, and S, making it suitable for mild and alloyed steels, stainless steels, and titanium alloys. It is installed by machinists and CNC operators working with DR-TWIST compatible drill bodies. The DT chipbreaker geometry is optimized for through-hole and blind-hole drilling at typical production feeds and speeds for the covered material grades.

Compatibility

Designed for use with ISCAR DR-TWIST series indexable drill bodies that accept SOMT06 style inserts. Verify seat geometry and clamping requirements against the specific drill body before installation.

Installation Notes

Installation is performed by machinists and CNC tooling technicians. Always power down and lock out the machine before changing inserts. Use the correct torx or hex key specified for the clamping screw of the drill body seat to avoid stripping or over-torquing. Inspect the insert pocket for chips or debris before seating the insert, and confirm proper indexing before resuming machine operation.
