NEIKO 02638A 5-Inch Automatic Center Punch for Metal, Adjustable Impact Spring Loaded Center Punch Tool, Spring Punch, Center Punch Spring Loaded, Auto Center Punch

Best punch I have ever bought and I have owned a lot over the years. No tool bag should be without one. It's a punch made of good quality and easy to use. Not much more to say.

Works great! Enough said.

Japanese quality! Works perfectly. Well made tool! I'm proud to own this tool. I plan to buy more for my grandsons and son-in-law.

It works as described, nice tool to have when drilling in a slippery metal surface.

So for decades I've been using my dad's old manual center punch (the kind you hit with a hammer) which has always worked just fine for me. But I watched a video of a guy using one of these self-contained center punches and thought I'd give it a go since the item was surprisingly affordable. I wasn't expecting anything too fantastic or even useful. I was delighted to discover that this thing works FANTASTICALLY! Nobody could be more surprised than me. I used it on metal (mostly aluminum and steel) so I crank it down to the "strongest" setting, ie giving the hardest "punch", and it leaves a very impressive divot that is easy for a drill to stay centered on. It's use is so easy that I typically trigger this device 3-4 times in quick succession jus to ensure I have a good dent made but I'm pretty sure just a single punch would answer the mail as far as drilling goes. One single triggering of this punch gives at least as good a result as my dad's old center punch that I have to hit with the hammer, probably better; unquestionably much better if I trigger multiple times in quick succession. It is now the only punch I use, since it is so convenient not having to grab a big hammer along with the punch to make a starting divot. And easily done with just one hand to boot! I highly recommend!

I have bought about 5 other 22mm chisels to punch out holes in 1/16 abs plastic. This is the only one that held up.I honestly had no business using chisels to punch out holes on this scale, but it was all I had to work with in the short term. After punching over 10,000 holes in plastic my chisel had finally broke.Some people would be discouraged over this, but I couldn’t be more impressed that it held up for as long as it did. I beat this poor tool to death and finally broke it on the second to last plastic sheet I was working on.I’m recommending this arc punch set to anyone that is looking at the competition. I have used them all, and I have broken them all. This one was the sharpest, toughest, and most durable one I’ve encountered.The only downside was having to unscrew the punch to remove the plastic circles. Time was the price I paid for quality, durability, and consistency. 5 stars for my ol broken arc punch that served me well.

Packaging says made in China. No instructions. Bought this to create a supply of plastic washers. Have punched out about 150 of these in 3 sizes. Generally worked great. Found 3 issues. As you punch, the cutter tends to vibrate loose, and you need to keep checking/tightening it. 2nd is that one time the screw which holds in the center point came loose enough that the whole point and spring popped out. Replacing the screw with a nylon tipped version or brass screw might be a better solution. 3rd is that there is some play with the center point but was surprised that in use it mostly marks the punched piece in the center. This of course is very helpful to perform concentric punches when creating washers where the inner dia is punched as the 2nd operation. The point screw needs to be in a position loose enough to allow free movement of the point yet set deep enough to retain the point. The punches are sharp, so that in many cases required only one blow to make the cut and hard enough that they held their edge. The machine finish on the punches is excellent. Supplied case is well fitted to keep punch heads in place. Not perfect yet pleased with this very good value.

I previously used a generic import punch until it failed. This is a substantially better punch and yet still reasonably priced. The tip is much more durable and the punching force is much stronger. It leaves a clear deep indentation that easily keeps a drill bit centered.
