Ben,

Regular drill bit, but I can’t remember the size for the hole at the moment, but will check tomorrow when I go out to the shop. Set-up a drill stop so you don’t drill completely through the back of your drawer box. That doesn’t hurt anything if you do, but you don’t have to have the hole all the way thru, just enough for the tab to fit.
