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

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

Cant beat the price, good quality

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.

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.

I like how good they worked

Made a small prick in both aluminum and hard steel. Although I thought it worked fine I believe a slightly stronger spring would improve it. I used it full tension but would liked slightly more resistance for a little deeper hole.

Neither item work directly out of the box!

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

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.

If you have to drill holes in ...... you can simply start drilling and hope the drill bit actually goes in straight. On metal or on rounded surface you know the drill bit will dance around before catching and scraping up the surface as it goes. These center punches are spring loaded so you simply place it where you want to drill press and it leaves an indent keeping your drill bit centered and straight. A must have for anyone working on metal or plastics. Good quality tool which when you learn how to use you wont ever not want to be without.
