Irwin products are always first class. I'm always surprised when I accidentally stick one of their bats in a nail that the Irwin bats take it like a champ. Nail, on the other hand, doesn't seem all that great. Comes with a large selection of bits. No Allen or Torx socket wrenches are included in this set. But there are many square springs, as well as many cross and flat springs. The Phillips heads have a good secure grip on the screws and this helps the screw to be installed more easily with one hand. All in all, it's a handy way to supplement missing bits and get some really great drills.
