A noticeable feature of SD Shank Drill Bits is that they have more buttons, which increases the energy released when drilling. The bits also include the global leader hard alloys, resulting in less wear, longer service life and fewer interruptions.With improved heat treatment and increased face hardness, the body is harder, tougher and sturdier. That means premium performance and longer service.
