[QUOTE="Raoul Duke, post: 2701131, member: 27529"] Take a punch or pointed cold chisel, hit it with a hammer on your layout mark, this will help keep the bit from walking as bad when you initially start drilling the hole. Start with a smaller diameter drill bit, maybe 1/4 to 3/8, as a pilot hole first. Use tape on the bit to mark the depth you want. Don't drill more than 3/4 to 1 inch at a time without backing the drill out while running to clear material from the hole as you drill. Pray you don't hit rebar. [/QUOTE]
