Many electricians and plumbers rely on Milwaukee's Selfeed bits for large hole drilling in wood. The inside cutting plane shaves the hole radius for clean smooth holes without pressure. A removable, replaceable feed screw draws the bit into the gummiest of woods effortlessly. A hex shank provides a secure gripping surface for the drill chuck. The bit is coated with a rust inhibitor.
