The Milwaukee® 3/8" x 18" Bellhanger Bit is designed for installing all types of small wire systems including computer, security, phone, and cable. Milwaukee Bellhanger Bits provide extra reach, and a hole in the tip for pulling wires through holes. The bits feature aggressive tip geometry for fast cutting, and non-stick coated flutes, for fast chip removal and reduced binding. The 3-Flat Secure-Grip™;;; shank helps prevent the bits from spinning in the drill chuck. Milwaukee Bellhanger bits are available in 12", 18" and 24" lengths.
