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

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.

Doesnt work like it suppose to . Cheap made and no good to me !

I use these mostly to make an indent for drilling. They work well for that. Ive used them on Aluminum and steel. I recommend clicking them several times to make a good indent so the drill bit stay where it should when starting to drill. You can also use these to break a car window in case you are trapped inside or you need to rescue someone. The parts are all metal and seem to be machined accurate enough to work well. Ive used similar punches that cost many times as much as these and they work pretty much the same.

I have been quite pleased with these! They work great, are adjustable and seem to be well made! - Perfectly simple to use! - Just press your tip point at the very spot you want your bit or screw to start, and press the body down - You’ll feel the quick “pop” of the tool and that’s it! (Use the adjustment to twist yours for more or less spring force) - Absolutely no other tool or hammer required, just point and press! - Would absolutely recommend these! 10/10 a win for me!

Not much you can say about a center punch. Pros: They work well. I like the colored body b/c it makes the easier to see. Its nice to have a set of two. Cons: They both jammed on first use and didnt spring back. I suspect an assembly problem. I unscrewed the body took the parts out and reassembled. Theyve been fine since.

Cant beat the price, good quality

I dont think these are fully stainless steel, but thats somewhat expected at this price point. Both of my punches work as intended and require a pretty average amount of pressure to fully engage the punch. I havent tried messing with the spring intensity yet because there was no need, but you should be able to make it firmer or softer depending on your application. Just based on the price I doubt these will last a long time but worst case I have a couple backup/throw away punches as needed.

Replaced a 30 year old punch and these are great! So far the points seem to hold up well and the spring action is great.

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.

Easily adjustable striker. Works perfectly. Built well.
