2 Pack Automatic Center Punch, 5 inch Heavy Duty Steel Spring Loaded Center Hole Punch with Adjustable Tension Punch Tool for Metal Wood Glass Plastic Suitable for DIY lovers

Absolutely terrible item! One of them broke after a handful of uses and the other one was already broke! Do not waste you money on this item! Ridiculous!!!

Like the extra tips

Bought it to break Glass. Would not use it as a punch for drilling as it does not have enough power for that. Tested it on mild steel and could barley see any mark at all. Aluminum it might work as I can see a mark that may be big enough for drilling, but it would have to be a tiny bit to get it started. Anyway. Bought it to escape an automobile as I will be driving a Tesla Model 3 and I will need to get out if my lipos start to arc for what ever reason. 6500 degrees if that starts.. I am getting out!!

This thing did not work right straight out of the box. The only reason it even got 2 stars is because I was able to use parts from this to fix my old one. The little piece inside with the hole in it that makes the whole thing function is so soft it dents in immediately and wont function.

These are accurate, solid built, and the spring has an effective impact on wood and aluminum. Definitely worth the money, and I would buy this punch set again and recommend it as an ideal gift for any DIYer or woodworker.

Jams easily

The spring isnt strong enough to hold up. Had to hit the same spot 6 or 7 times

Got these to punch rivets out of a car window regulator with a hammer so I could drill them out. Got the job done!

Decent tool for the price. It isnt something we use daily, but it has worked well when needed.

I treated myself to these spring loaded center punches for workings in my hobby shop; mostly on metals. The price is very fair. As mentioned in other reviews; one of the units is needing some internal repairs to ensure the punch reloads for repetitive punches. It does not always return to the offset internal position for pushing on punch spring loads. It does include 2 extra pins and they are chrome plated to enhance durability. The punch points are needing a bit more striking angle and point, but that would decrease point longevity. All in all, I would purchase this product for the price again.
