    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.

    Cant say enough good things about this set of spring loaded punches. They work perfectly and like they are supposed to. The knurling provides a nice grip. Both sides can be unscrewed for cleaning and lubrication. You really cannot go wrong with this set. They are an excellent value. I have a Starrett at work that cost ten times as much as these two. They make the same indent on steel as the Starrett does. They even feel the same when used. I would highly recommend these center punches. Extremely useful tool to have on hand.

    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!

    The tool is inconsistent. I rarely works as intended.

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

    I dont think these are fully stainless steel, but thats somewhat expected at this price point. Both of my punches work as intended and require a pretty average amount of pressure to fully engage the punch. I havent tried messing with the spring intensity yet because there was no need, but you should be able to make it firmer or softer depending on your application. Just based on the price I doubt these will last a long time but worst case I have a couple backup/throw away punches as needed.

    Not much you can say about a center punch. Pros: They work well. I like the colored body b/c it makes the easier to see. Its nice to have a set of two. Cons: They both jammed on first use and didnt spring back. I suspect an assembly problem. I unscrewed the body took the parts out and reassembled. Theyve been fine since.

    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.

    These seem well-built and sturdy, although the mechanism is a little stiff (maybe after I use it for a while, it will become smoother). I used it to make a few drill guides in a wood beam, and it worked just fine. One small negative is that if you dont know how to adjust the tension, these came with no instructions whatsoever. Fortunately its not hard to find this info online (or figure it out): the farther you unscrew the base (the end farthest away from the point) the less tension there is on the mechanism and the less force needed.

This punch is super easy to use, You can adjust the tension in the spring by twisting the top, put point where you want a mark, then depress the top end until it clicks and pops and the mark is made. It keeps the drill bit from roaming about during the initial drill process.
