Sandvik Coromant 7549924 Indexable Drill Insert DS20

Product Description

The SANDVIK COROMANT 7549924 is a solid carbide indexable drill insert designed for use in indexable drill tooling systems. This insert features a DS20 insert style with an M7W chipbreaker geometry and carries manufacturer grade 4334, a CVD-applied multilayer coating of TiCN, Al2O3, and TiN that resists heat and abrasive wear during drilling operations. The irregular insert shape and 0.6 mm corner radius suit demanding cutting applications where edge stability and coating durability are essential. Installation is performed by qualified machinists and tooling technicians working with compatible indexable drill bodies.

This insert is suited for indexable drill applications in metalworking and machining environments, including general-purpose drilling in steel, cast iron, and other machinable alloys where CVD-coated carbide grades are recommended. The M7W chipbreaker promotes effective chip control across a range of feed rates and cutting depths. The insert size designation is 0306, and the part is sold individually per package with a minimum order quantity of 10 units, making it appropriate for shop stocking and production-run replenishment.

Installation Notes

Installation of indexable drill inserts should be performed by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is locked out before changing inserts. Use the appropriate torx or hex key as specified by the drill body manufacturer to seat and torque the insert clamp screw. Inspect the insert pocket and clamp for debris or damage before seating the new insert.
