Automatic Center Punch Set, 2 Pack 6 & 5 Automatic Centre Hole Punch, Super Strong Adjustable Impact Center Hole Punch Tool, Marker Scribe Spring Loaded Punch Tool for Glass Metal or Wood

There is better out there for sure. Wish I would had spent 5 more dollars.

Only use it a few times before the tips got no and one of the springs I had to change out already in the big one my opinion not worth the money

The bigger one doesn’t even have enough of a strike to leave mark, I’m assuming the spring assembly is messed up ? Who knows, the little one works about 2 out of 5 times, both the ends have rounded after just testing them out! Go to harbor freight and get the 4$ spring punch. Looks identical to the small one and works wayyy better. I already tossed these 2 in the trash.
