The kids in SwampMan’s class kept breaking the 7/32 drill bits used for predrilling holes for drywall screws used in their small wooden projects (drywall screws being cheaper and smaller than wood screws). SwampMan cut the head off a 6 penny nail and put it in the drill for them to use instead. It works very well. Don’t make the mistake of touching it, though!
