Sandvik Coromant 7549982 Indexable Drill Insert DS20

Product Description

The SANDVIK COROMANT 7549982 is a solid carbide indexable drill insert designed for use with the CoroDrill DS20 drilling system. Manufactured to grade 1144 with a PVD-applied TiAlN and AlCr2O3 coating, this insert delivers wear resistance and thermal stability in demanding hole-making operations. It features an irregular shape with an inscribed circle of 17.46 mm and a corner radius of 0.35 mm. The DS20L5 chipbreaker geometry promotes controlled chip formation. This insert is installed and serviced by machinists and tooling technicians working in precision metalworking environments.

This insert is intended for use in the CoroDrill DS20 indexable drill system, compatible with DS20-style insert seats. It is suited for drilling operations in ferrous and non-ferrous materials across general machining, die and mold, and production turning environments. The L5 chipbreaker designation makes it appropriate for a range of feed and depth-of-cut conditions typical of indexed drilling applications in both manual and CNC setups.

Installation Notes

Indexable drill inserts should be installed by qualified tooling technicians or machinists following the drill body manufacturer's torque and seating procedures. Ensure the spindle is fully stopped and the machine is locked out before handling inserts. Inspect the insert pocket for debris or wear before seating a new insert. Use only the designated torx or hex key recommended for the DS20 clamping system to avoid insert or pocket damage.
