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

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.

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

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.

very good product...

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

great for woodworking also

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.

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

It came fast and is exactly what I was looking for
