Big hole solution

Step drill bit set I bought sheet metal and plywood cutters with no problem. When not drilling a hole, the accuracy of the chisel is great. However, drilling "in-between" sized holes is challenging as the drill bits are aggressive. I haven't had a set yet and haven't used all the bits yet, durability is really unknown. I also don't know how long the bits stay sharp. I like the small metal housing very much, it's a pity that the grain doesn't fit in the box.

Pros
  • Automatic punch: A punch with a spring inside automatically creates more punch and a red cap on top saves power
Cons
  • There are more interesting options.
