Starrett Steel Automatic Center Punch with Adjustable Stroke - 5-1/4 Length, 11/16 Punch Diameter, Lightweight, Knurled Steel Handle - 18C

I bought one of these over thirty five years ago but i thought i lost it so i bought this one it looks exactly like my first one except for a little strip of knurling about a half inch from the point outside of that they are exactly the same and before this one arrived i found my old one just the name starrett stands for high quality and durability because of that i now have two of them they are made in the U.S.A because of that and the name you just cant go wrong i would definitely recommend this tool to everyone fast shipping and high quality you cant go wrong.

As stated in the title, I run a metalfab shop. I use this nearly every day, and have punched what must be hundreds of centers in mild steel with this. Its still sharp and working like the day I pulled it from the box for the first time. Having it be adjustable is nice too, when using it on softer/thinner materials or for smaller holes, where more force or larger centers arent necessarily a good thing. Ive learned to love this center punch, highly recommend it, and will be a repeat customer.

The day I received my 18C from Amazon, I tried using it on some suitable aluminum stock, to get familiar with it and see how its adjustment works. For a while, I couldnt get it to fire at all, even though I was adjusting it correctly: I turned the end cap so the spring nearest the user would be compressed less. Finally, I loosened the threaded sleeve near the tip, even though I figured that that sleeve isnt there for any adjustment purpose (I found out later I was right). After loosening the sleeve near the tip a bit, I could get it to fire about 50% of the time. I wanted to see whether, in fact, the only adjustment on the tool is performed by turning the end cap; so I looked on the Starrett website for an instruction manual. (As other reviewers have pointed out, none of the Starrett automatic center punches come with any instructions, probably because the company believes that anyone who buys a Starrett tool must already know what hes doing.) There is no instruction manual available on the Starrett website either. I called Starrett using the toll-free phone number on the website. The nice tech support person I talked with told me: Yes, the only adjustment on the tool is via the end cap, and the threaded sleeve near the tip should not be loose prior to using the tool. I explained that I could only get the punch to fire if I slightly loosened the threaded sleeve near the tip; even though I had loosened the end cap quite a bit. I also said that even after I did those 2 things, the punch would only fire about half the time; based on at least 50 attempts. I asked the Starrett tech support person whether I might have a defective item. He said I might have, and I should probably exchange it for a different example. Im kind of disappointed. This is the first Starrett tool Ive ever purchased, and it took me a while to talk myself into paying what I did for it. (By the way, I think Amazons price is very good: as I recall, its the lowest I saw, and of course shipping is free for an Amazon Prime member.) I may purchase a Starrett 18A, which is also a current Starrett product. The length of that unit is 4.85 in, according to the drawing I downloaded from the Starrett website; its largest diameter is slightly less than that of the 18C; and according to the website, the spring near the end cap has a smaller diameter than the one in the 18C. So the 18A should apply less force to the material than the 18C. That would be fine with me. I think the 18C would apply too much force for most of the work I do. Strangely, I see that if I purchase a Starrett 18A on Amazon, it would be through an Amazon reseller, so I would have to pay a shipping fee. If I do purchase another Starrett automatic center punch, Ill cross my fingers and hope that I dont get another defective example. By the way, 18C that I received is beautifully machined and seems to be well designed. I even took it apart, and I dont see anything wrong with it. Given all that, Im very surprised that I can only get it to fire about 50% of the time.

If you are looking at the reviews this is already the product for you cause you must care about quality. It’s built like a brick wall. It’s made to last. Most importantly it’s made in America. Not much more to say.

This is for the person who cares about quality more than how much it cost. It is worth every penny.

A little bit pricey compared to similar items but it’s true that you get what you pay for even in these modern times - at least sometimes… The thing is a beast I thought I needed the “heavy duty“ model which is the 18C and it turns out that I absolutely did not need the heavy duty model but will be keeping it just because it’s quite the lovely tool to use. I will definitely have to get the 18A to round out the set though. Of course the reason that I was under the impression that I should get the heavy duty model (compared to the 18A which is the lighter duty model of the same design), is because of my past experiences with so-called heavy duty automatic punches… Needless to say, Starrett’s 18C sort of immediately redefined the meaning of heavy duty for me.

I was hesitant to spend this much money on an automatic center punch, but am glad that I did. This is a very high quality tool that is not only a pleasure to use but should last a lifetime. There are parts (such as the tip and spring) that may need replacing after a lot of use, but as with many quality tools you can buy those parts without having to buy a new tool. I took a star away because I had to use pliers to start the adjustment cap turning and once the cap was broken free hand turning wasnt smooth and even. That was quickly fixed using a small brash brush and air compressor to remove what looked like small metal particles in the threads. Once that was done cap adjustments were smooth and easy. I was also contemplating getting one of their lighter duty punches after reading some of the reviews. Im glad I didnt because this punch is versatile. Unlike some reviews, even at the highest tension setting I had no problem using the punch and the range of adjustments was significant. At the lightest setting I used it on hard wood, plastic and thin steel which made a larger dent than on heavier metal. Unless youre a weakling, this may be the only punch you need.

Not my father’s Starrett center punch. Doesn’t operate with the same clean smooth feel. And most important it does not appear to have the very hard and very tough grade of steel at the tip as the ones I grew up with: Punching mild steel with the Starrett punch set to highest force I could press (a lot), the mill finish on the test piece is barely touched. SAD!

Great automatic center punch. Very well made, solid, excellent machining. Made in Murica.

I always used a punch and hammer togeather. Now I am able to mark holes more quickly one handed which is especially nice when I need to drill several holes. Realizing that took away overspending concerns especially since Starrett makes high quality tools. I read some comments about the tool not resetting. I am not sure if it was the same issue I noticed but the tool would fail to reset after multiple punches. After some thought a Duh moment arrived and with it realizing I was not lifting the tool up fully from the stock after it clicked. Perhaps it has something to do with getting broken in. Since then the issue went away. The only other smidgeon of an issue is the black paint job on a small tool which can make for tedious searching. Next hardware order will include some bright color spray paint.
