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

The large one sucked no power at all the little one worked awesome very strong plenty of power

These are so handy for my jewelry making. Makes drilling holes so easy. I love them and they are very sturdy and easy to use.

great for woodworking also

This is one of those tools that you always think about buying but never seem to get around to it for one reason or another. With two automatic center punches made of real metal for under 5 bucks and free shipping, I couldnt pass it up. I think Ill buy another set for my son-in-law.

the larger one requires considerable force but leaves no visible mark on mild steel.

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.

Works well on cabinet hardware installation

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.

Absolutely garbage. Get a name brand or even a harbor freight one. These are not worth owning if they were free. Returned. Not returned because i needed my $8 back. Was more inconvenient that anything. I returned because whoever is making these deserves to not be making these sooner than later.

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
