I just took apart my built box and I have a bunch of MDF splits. I predrilled the holes, but the drill bit i used was too small for the drywall screws. Also i have a bunch of unwanted holes in the box. What do i do? Is there a fix, or should i buy new MDF? What screws/drill bit combination should i use? This sucks, I dont care about the extra 20+ dollars of MDF, just the work! Here are some pics.
