Drill bits for curved or angled access use a specialized shaft and guiding frame to direct the bit along an arc, helping route cable from near the floor into a wall cavity while reducing the need to remove baseboards. Standard drill bits typically create straight holes, so installers may need additional access or wall and floor work when routing cable through these areas.

Phillips power bits with a hex drive work with 1/4-inch drive manual screwdrivers and 1/4-inch or larger electric drills and drivers. They are available in multiple sizes for fastening applications.

For repeated low-voltage installation tasks, look for sturdy steel construction, including powder-coated steel frames and chrome vanadium steel bits, to support routine drilling and fastening work. Curved cable-shaft paddle bits can help guide wire from floor level into wall cavities, while hex-drive shafts fit compatible screwdrivers and electric drills.

Choose a drill bit that creates enough clearance for the wire or cable, including any connector or protective covering, while keeping the hole as small as practical for the installation. For fasteners, match the bit type and size to the fastener head, such as a number one Phillips power bit for compatible smaller Phillips-head screws, and confirm that the bit fits your drill or driver.
