Long installer drill bits for running cable and small lines through framing. The collection includes Diablo 1/4" x 18" and 3/8" x 18" installer drill bits for wood.
Installer bits have a cross hole near the tip so wire or pull string can be drawn back through the hole, and the long shank reaches through studs, plates and walls. Choose the diameter to suit the cable or tube being pulled, and use these for wood only. Drill slowly near concealed wiring and pipes.
