Yes, yet, cordless hydraulic punchout tools are used by many as well.those sets are one of the most expensive kits in an electrician's toolkit, but completely necessary when punching through panels.

if it bent the cobalt % must be very very low. Cobalt bits are very wear resistant but shatter.Sounds like they're better than the deWalt cobalt bits. This happened with the first hole I drilled with this bit. Just as it broke through it jammed, as sometimes happens, and this was the result. This was with a handheld drill, not a drill press, and I'm a weak old man that can't exactly exert a lot of torque through my wrist. Not recommended.View attachment 18248
