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

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.

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.

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

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.

It came fast and is exactly what I was looking for

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

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.

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.

Too cheaply built.
