SANDVIK Coromant has introduced a new drill concept for automotive and aerospace applications.

This high precision carbide drill offers the potential to completely replace PCD drills in many aluminium drilling operations.

The Delta-C Al drill focuses on ISO-N materials, particularly aluminium alloys with an Si content of 8-12% or less.

Hole tolerance and quality are enhanced while burr formation is dramatically reduced, thanks to a unique geometry specially designed for aluminium.

The Delta-C Al drill is available as tailor-made in diameters 3-20mm, with or without internal cutting fluid supply, and in five different drill types.
