The Milwaukee 3/8" x 54" Cable Bit is ideal for installing small wire systems in unreachable spaces. Milwaukee Cable Bits have an extra long, flexible steel shaft that lets you reach behind the wall with greater precision and ease when installing all types of small wire systems, including computer, security, phone, and cable. The bits feature holes in both ends to pull the wire through after drilling. Use the Milwaukee Placement Guide (48-08-0275) to properly locate the hole within the interior of the wall. Milwaukee Cable Bits are available in 54" and 72" lengths.
