For most Ring doorbells, you’ll use a small bit for wood and a larger one for masonry, matching the included wall plugs.

Quick Scoop

  • For brick, concrete, or masonry : use about a 1/4" (6 mm) masonry drill bit so the supplied wall anchors fit snugly.
  • For wood (no wall plugs) : use a bit around 3 mm (roughly 1/8") as a pilot hole so the screws can bite firmly without splitting the wood.
  • Always check your specific Ring model’s install guide, as some wired “Pro” models explicitly call for a 1/4" (6 mm) bit for the pilot holes with anchors.

Simple rule of thumb

  • If you are using anchors : match the bit size printed on the anchor packaging (commonly 6 mm / 1/4").
  • If you are drilling pilot holes just for screws in wood : pick a bit that is slightly thinner than the screw’s shank (usually around 1/2 to 3/4 the screw’s diameter).

Mini example

If you’re mounting a Ring battery doorbell on a brick wall with the supplied plastic anchors, choose a 1/4" (6 mm) masonry bit, drill the four holes, tap in the anchors, then drive the screws through the Ring bracket into the anchors.
