Fishing Electrical Wire Through Walls
Wires aren't supposed to be installed any closer than 1-1/4 in. from a penetrable surface (the outside of the drywall). That means you shouldn't be drilling holes right next to the drywall. But it's not always easy to control where a flex bit goes. A Bumper Ball flexible drill bit guide installed on the end of your flex bit will help maintain the proper space between the bit and the outside of the wall cavity. You can buy a set of two at electrical suppliers or at licensedelectrician.com.
