What drill bit do you use for rock?
What drill bit do you use for rock? Insert a carbide- or diamond-tipped masonry drill bit into the drill. Do this by loosening the chuck of the drill, inserting the end of the and then tightening the chuck of the drill back up. Do not attempt to use a wood bit to drill into rock, as doing so can result in the bit breaking which can cause serious injury. What size drill bits do I need? Use a bit 1/64” smaller than the target hole size for softwoods. Use a bit exactly the same size as the hole when working...
