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

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

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.

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.

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.

cheap, but junk. ordered first pair, one worked. ordered replacement pair on amazon, neither worked.

This is a usable and functional low budget center punch. The product listing indicates it’s made of “high-quality stainless steel” but it appears to be run of the mill steel. I saw no difference when I adjusted the spring tension and used the punch on 1/8” thick mild steel and the resulting dimple wasn’t very deep at any spring tension. That said, it’s usable and there’s admittedly little to complain about given the $6 price for 2 punches.

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.

Easily adjustable striker. Works perfectly. Built well.

I like how good they worked
