Cobalt drills from Atlas Cutting Tools are a preferred drill for harder materials especially stainless steel. The primary reason for this being they hold rigidity and hardness at a higher temperature than HSS drill bits. Cobalt drills are more suited to CNC machines, Pillar Drills and Drill Presses due to the brittleness of the material compared to standard HSS – High Speed Steel.
