Sandvik Coromant 7549971 Indexable Drill Insert DS20L5W

Product Description

The SANDVIK COROMANT 7549971 is a solid carbide indexable drill insert designed for use with the CoroDrill DS20 drilling system. It carries the DS20L5W insert style with a 2044 manufacturer grade and features a PVD-applied TiAlN and AlCr2O3 dual-layer coating for wear resistance at elevated cutting temperatures. The irregular insert shape and L5W chipbreaker geometry work together to control chip formation in demanding drilling applications. With a corner radius of 0.8 mm, this insert suits precision hole-making operations where controlled chip evacuation and edge integrity are critical. It is a right-hand cutting insert intended for professional machining environments.

This insert is designed for use in CoroDrill DS20 indexable drill bodies, size 0608, in both CNC turning-center and machining-center applications. It is suited for productive drilling in ferrous materials where PVD-coated carbide inserts deliver consistent tool life. Machinists and toolroom professionals working in production or job-shop environments will find this insert appropriate for mid-range drilling depths requiring reliable chip control. Compatible drill style is DS20, and the insert size designation is 0608.
