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.

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.

Cant beat the price, good quality

I really like these centering punches. Ive been working on a project that involves drilling dozens of holes in mild steel. My old punch (another automatic) never left a satisfying dimple to start a drill bit. It would leave a mark to line things us, but it wasnt deep enough to ensure that the bit wouldnt wonder. Well not these punches! The point on these punches is sharp and suepr hard. The spring has a terrific punch to it and is strong enough to get a good start in any metal or wood surface. My drill bits of various sizes were always right on center following the dimple from these punches. Highly recommended.

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

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.

The center hole punch is pretty good. Its easy to use and it comes in handy when youre drilling through a hard or a slippery surface. The tension is easy to adjust and it has a pretty good range. The smallest holes in my pic are at the lowest setting punching through pine. Good thing you get a set of 2 because the center hold punch is tiny and easy to lose in a busy shop.
