Our 1/1" x 72" Flexible Cable Auger Bit provides flexible drilling and clean holes when installing small wire systems in unreachable spaces. The screw-tip design allows for faster wood boring. The dual pull-through hole design features holes on both ends for feeding wire through drilled holes. The auger-style flute allows for faster drilling and easy chip ejection. The flexible shaft allows you to drill inside walls or between floors with greater precision and ease when installing all types of small wire systems, including computer, security, phone, and cable. The 3-FLAT SECURE-GRIP™ prevents the auger bit from slipping in the chuck. The reusable case protects the bit. The cable auger bit is for use with drills. Cable bit accessories are sold separately.
