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.

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.

Too cheaply built.

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.

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.

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

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

junk dont waste your money

There is better out there for sure. Wish I would had spent 5 more dollars.
