2Pcs Heavy Duty Automatic Center Punch, 5 Premium Steel Spring Loaded Center Hole Punch, Adjustable Spring Impact Center Marker Scriber Tool for Metel, Plastics, Wood, Glass by karmiero

Its easy to use for pushing down but if you have a project which requires a push upwards or sideways, this tool isnt strong enough.

I really like these centering punches. Ive been working on a project that involves drilling dozens of holes in mild steel. My old punch (another automatic) never left a satisfying dimple to start a drill bit. It would leave a mark to line things us, but it wasnt deep enough to ensure that the bit wouldnt wonder. Well not these punches! The point on these punches is sharp and suepr hard. The spring has a terrific punch to it and is strong enough to get a good start in any metal or wood surface. My drill bits of various sizes were always right on center following the dimple from these punches. Highly recommended.

Neither item work directly out of the box!

This offer was for 2 identical punches at a low price. Very handy to have in 2 different locations. I dont know how long they will last, time and use will tell.

These are like other import automatic center punches Ive used. Fits nicely in the hand. The punch is a bit wobbly in the handle, but it gets the job done. Its made of carbon steel, not SS. There is no real spring tension adjustment, it just screws apart and back together. Not sure what youd need to adjust the tension for, anyway. Two of these cost less than the sales tax on the premo US made one these are made to look like. No comparison, of course, but I used one of them to make multiple dimples in a sheet metal plenum for the center pivot of a compass so I could mark take-off holes. It did the job just fine.

cheap, but junk. ordered first pair, one worked. ordered replacement pair on amazon, neither worked.

This is a usable and functional low budget center punch. The product listing indicates it’s made of “high-quality stainless steel” but it appears to be run of the mill steel. I saw no difference when I adjusted the spring tension and used the punch on 1/8” thick mild steel and the resulting dimple wasn’t very deep at any spring tension. That said, it’s usable and there’s admittedly little to complain about given the $6 price for 2 punches.

Wasnt sure if I could use this with not much hand strength; but this was easier than I thought. I kept losing the little pre-drill screws. This was a great find. And TWO for the price was even better.
