Each of these large-size bits has a reduced shank to fit your standard-size drill. And each is constructed to drill large-diameter holes in steel, wood and other building materials with ease. The Cobalt coating is the key to this. It penetrates 80% faster and keeps a sharp edge longer. Plus, you can keep the whole set together and take it with you in the molded carrying case. No workbench would be complete without it!
