ALLY Tools Super Strong 6 Inch and 5 Inch Heavy Duty Automatic Center Punch, Perfect Automatic Center Punch for Metal, Wood, Plastic, Glass, and Marble – Features Spring Loaded Center Punch Design

These center punches were purchased for use around the home. I do not know how they would perform for commercial use but the price and function are satisfactory for me.

I took the two out the package and went to test them immediately. With wood them both worked great. Then metal… the small one was ok…. Felt alittle flimsy but worked with 10 punches in three types of metal. The bigger one only punched 4 times then stayed depressed in the down position and never came back up. Broke on the 4th metal punch. Finally bought a different one and it’s punched over 40 times and is still going. I may have gotten a bad one but two for the price of one in this case isn’t worth it. Get a different one, I can’t in good conscience recommend this item.

Both punch same holes when used, fully tighten. In a 3/16 mild steel flat bar, these make same 1/32 punch holes. Make note of that drill bit size.. These will work on aluminum but thats not steel and the description should be changed or spring tension should be increased.. How do you test your punches??? Ill stick to my basic hammer punches, at least I can start with a 3/16 bit.

Awesome automatic punch set for the money. I would recommend to anyone!

verry weak springs

My husband got these center punches and really likes them. They work well, with a nice indent. He only wishes that both punches would have a ball to fit in the palm of your hand instead of just one, and it doesnt seem that that one comes off to interchange. That was an easy fix for him so it wasnt a deal breaker.

My first product was defective and I tried to remedy it by oiling it. It does improve but still not well enough. I contacted the seller and the seller was friendly and helpful. Once found that my product is defective, seller send replacement very quickly. New product arrived perfect from Amazon warehouse. It works out of the box and I really like the adjustable tension.

My older punch broke after only 40+ years. Eben if these only last a fraction of the time, they are a great buy

Nice punch with a strong spring and accurate centering

The punches work OK if you are careful. The action is not smooth, even after oiling. They produce an approximate center mark, not exact. I expected more for the price.
