impact chisel work like auto dot punch

[whensparksfly]

I seen some large impact chisel or puches that work like auto dot punch but can't seem to find the on the internet

when i was an apprentice i had a small set with different heads that screwed on, line it up on the work and then use like an auto punch...it was pathetic but im sure it came from cromwell

Sounds very much like an impact driver, I/2" square drive . can be used with large screw driver hex bits etc
