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

Good product and well made.

Both worked but do not mark metal very well for starting drill bits to keep them from traveling. They would work great for breaking glass in a vehicle if thats what you are looking for. The spring could be stronger.

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.
