The Milwaukee 48-25-4621 is a 4-5/8 in. Selfeed Bit. 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.
