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

These seem well-built and sturdy, although the mechanism is a little stiff (maybe after I use it for a while, it will become smoother). I used it to make a few drill guides in a wood beam, and it worked just fine. One small negative is that if you dont know how to adjust the tension, these came with no instructions whatsoever. Fortunately its not hard to find this info online (or figure it out): the farther you unscrew the base (the end farthest away from the point) the less tension there is on the mechanism and the less force needed.

Love these punches. They are solid, heavy-duty and quality punches. I have a lot of punches - all are really old. I was in the market for new ones and decided to give these a try. I really like them. Love that they have a little give with the adjustable spring impact. That helps tremendously during use. Simply turn it for more or less spring. These will get a ton of use too! Definitely a great price at $5 for a pair of these.

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.

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.

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.

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.

Item description: Automatic Center Punch x2 Brand: Karmiero Item: B0BR8B8XKJ Date received: 2023-03-09 Headline - Nice value; good to have one in each toolbox, and useful in the car as well. Product Claims 2 ct Automatic Center Punch I received exactly what was claimed in the product description as to quantity (2 ct) and type (automatic center punch). The items came in a white pasteboard box, each within its own heat-sealed plastic bag. There were no instructions for these (none really are needed). Each item is purely mechanical, operated by spring/ratchet action. You merely push down with the pointy tip at the place you want a starting punch, and the spring loaded internal hammer loads up and knocks the point into the material. If you need a deeper mark, or the material is hard, you can repeat this action several times to create a larger mark. These also have utility to keep in your car, as a window breaker, in case you end up in high water due to going off the road or mistakenly driving into deep water during a flood or hurricane. These are relatively inexpensively made, based on a now-standard long-ago design (my grandfather, a machinist in his early years known for making many of his own tools, made his own automatic center punch to essentially this design, circa the 1920s), but they are solid steel and should last awhile if you are using them in soft or moderately hard materials. You can touch up the point with a grinder or sharpening stone as needed. The point of these is probably not hard enough to put a mark into a hardened steel.

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

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.
