If you’re running cable through studs, plates, or other wood framing, the Greycore Tools 9/16″ x 54″ Flexible Drill Bit is built to make the job smoother. Its long, flexible shank helps you maneuver in tight wall spaces, while the auger-style cutting head and screw point tip are designed to bite into wood and keep the bit moving forward.

For pulling wire, this installer bit includes fish eye holes on both ends—handy when you need to pull from either direction without backing out and re-threading. It also uses a 3-flat shank (3/16″ diameter) that’s compatible with standard 3-point drill chucks and helps reduce slipping during drilling.

  • 9/16″ x 54″ installer-style flexible drill bit with auger head
  • Fish eye holes on both ends for pulling wire from either direction
  • 3-flat 3/16″ shank fits standard 3-point drill chucks and helps resist slippage
  • High Speed Steel (HSS) one-piece design with machine-sharpened cutting head and screw point tip
  • Designed to drill through wood, including hardwoods, softwoods, plywood, and OSB

This is a solid pick for DIYers and pros who want a longer installer bit for routing wire in walls and other enclosed spaces where a standard-length bit won’t reach.
