Iscar 5506611 SOMX05DT IC9080 Indexable Drill Insert

Product Description

The ISCAR 5506611 is a square indexable drill insert carrying the SOMX 050204-DT IC9080 designation, designed for use in DR-TWIST series indexable drilling systems. Manufactured from solid carbide with a CVD-applied IC9080 coating, this insert delivers consistent cutting performance in demanding production environments. The 90-degree included angle and DT chipbreaker geometry work together to control chip evacuation during deep-hole drilling operations. The inscribed circle measures 0.2126 inches (5.40 mm) and the insert thickness is 0.0945 inches, placing it in the 05 insert size class. Licensed machinists and CNC operators working in high-volume metal removal applications specify this insert for its grade stability under thermal load.

This insert is intended for indexable twist drill bodies in the DR-TWIST series and is suited for both residential shop and industrial production environments. Primary workpiece materials include cast iron (ISO code K) and steel (ISO code P), making it a practical choice for general machining, mold work, and structural steel drilling applications. The DT chipbreaker designation indicates geometry optimized for controlled chip formation across these material groups. This insert is sold individually with a minimum order quantity of 10 units.

Key Features

Installation Notes

Indexable drill inserts of this type are seated and secured by a machinist or CNC operator following the drill body manufacturer's torque and clamping specifications. Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Always verify insert orientation and engagement before resuming cutting operations.
