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

karmiero 2 Pc Automatic Center Punch Remarkably, both of the spring-loaded automatic punches worked the first time. The grip is easy to maintain. First, I tried various types of wood. The pressure to activate the punch is minimal. Each time it scribed a hole mark. I then went to metals such as aluminum and steel. The steel required spring adjustment to get a good visible hole. The punch never slipped and was accurate. The tools are easy to assemble and disassemble. Well manufactured, and no detectable flaws. Excellent value.

I like how good they worked

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!

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

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.

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.

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.

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

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.
