  • 5PCS different sizes/levels of step bits that you'll appreciate the versatility and convenience they bring to your drilling tasks. Say goodbye to the hassle of switching between multiple bits.

Not too good on metal
Size: 5 Pieces
Well you know the saying, you get what you pay for, these look well made, similar to others I've used, the largest one I used today and it would not bore a hole I was trying to enlarge in a 1/4" piece of galvanized metal.... Live and learn, probably would work good on items made of plastic
