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

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!

I bought these on a whim just to see what the spring loaded punch would do. It works fine 90% of the time buy the mechanism needs to be tightened down occasionally or you do not get that crisp punch into the wood.

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.

This is a nice punch. Would have given 5 stars, but the first time I used it, the punch did not reload. I took the unit apart but found nothing I could see holding the spring. I banged it on the table and the spring released. After reassembling the punch worked perfectly and reset every-time.

It malfunctioned on 3rd use, not sure how long it will last.

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.

Given the cost I didnt expect a high caliber tool, but I figured since there would be *two* of them I would at least wind up with 1 usable tool. I was wrong. The first punch never fires and is functionally just an awl. The second punch fired *1* time and immediately became stuck so now its functionally a paper weight. I could likely find a way to fix it but Id rather not spend time fixing a tool before its first real use. Will return and purchase something else.

The mechanism in both United are very difficult to work. Need to repeatedly press the unit down more than once to have the spring disengage and spring back to make the mark. Is is easier to just use a scribe instead of the center points that I purchased. Not happy with the product unfortunately. Thank you.

IF yours doesnt punch holes, you have to open up the front part and change the direction of the spring. The spring that is closest to the hole punch part. For some reason the spring I received way put it backwards so it was catching on the mechanism inside and not pressing into the whole fully.
