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

junk dont waste your money

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.

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.

Stay away, The hammer mechanism in these low cost punches does not work often.

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

It came fast and is exactly what I was looking for

The smaller one is ok - hammers 90% of the time. The bigger one almost never actuates correctly. And I tried to adjust whatever can be adjusted.

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

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.

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.
