With the Bosch 2608584677 pilot drill bit, you create an accurate guide hole that stops your hole saw from wandering during initial contact. Made from heat-resistant HSS-Co cobalt alloy steel, this 80 mm bit handles tough friction when cutting into stainless steel sheets, metal profiles, pipes, plastics, and wood with metal. Its 1/4" hex shank fits seamlessly into Bosch Power Change arbors, giving you complete control for clean, concentric pass-through cutouts.
