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

Took very little to get it to punch which means it wouldnt strike the metal to make the digital most of the time. Then it just broke. No neglect, I was just using it and it broke. Do not buy this, absolute junk.

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.

Larger of the two punches stopped working the day after the return window. Cheap built and not much of a punch even when it works.
