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

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.

Love it

One didnt work at all and the other works kind of, but only 1 out of 2 times.

Neither item work directly out of the box!

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.

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.

The karmiero is decent and definitely more than expected for the price of $4.99 especially since it comes with two. It has worked well for my use so far but probably not made for daily shop use. This spring loaded center hole punch design uses adjustable Spring Tension screw, you only need to rotate the cover to get the suitable impact strength to leave an indentation on your surface. So far Ive used on wood and metal with. no problem.

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.
