Install small wire systems easily and efficiently with the Milwaukee 3/8 x 12 Bellhanger Bit. Designed for installing all types of small wire systems including computer, security, phone, and cable, Milwaukee Bellhanger Bits provide extra reach where needed and a hole in the tip to help pull wires through holes. The bits feature aggressive tip geometry for faster cutting and non-stick, coated flutes for fast chip removal and reduced binding. The 3-Flat Secure-Grip shank prevents the bits from spinning in the drill chuck. Milwaukee Bellhanger bits are available in 12, 18 and 24 lengths.
