Product Description

The SANDVIK COROMANT 6626843 is a solid carbide indexable drill insert designed for use in Sandvik 880-series indexable drills. This insert carries the 4324 manufacturer grade with a TiCN and Al2O3 coating applied through a CWD coating process, providing wear resistance and thermal protection during drilling operations. The square insert shape with an LM chipbreaker geometry controls chip evacuation in a range of workpiece materials. The inscribed circle measures 12.65 mm (0.4980 inches), and the corner radius is 1.00 mm (0.0394 inches). This insert is installed by machinists and CNC operators as a direct replacement component in indexable drill tooling assemblies.

This insert is suited for indexable drilling applications in metalworking environments including production machining, job shops, and manufacturing facilities. The right-hand cutting direction, square shape, and LM chipbreaker make it applicable across a variety of steel, stainless, and general-purpose machining operations where controlled chip formation and surface finish consistency are required. The insert size designation is 07P and the length is 12.65 mm.
