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.

great for woodworking also

It came fast and is exactly what I was looking for

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

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

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.

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

very good product...

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.

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.
