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 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.

Great compact solution to marking for drilling or layout plans on multiple surfaces.

It came fast and is exactly what I was looking for

Both the punches are weak. Will work good for wood, but not on metal. Multiple attempts and barely a point in a broken off bolt.

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

Just got my punched today the smaller one works good the bigger does not work at all very disappointed figure it would work

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.

junk dont waste your money
