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

This thing is a beast. Against my better judgement, Ive used a pos $3 HF and $10 General for years. For the cost, those are great but they just dont have that feel you get from a quality tool. This, is that tool. I wasnt sure if it was more than I needed based on other reviews and yes, it will punch a hole into the thickest of metal but Ive loved it since the first use. I now walk across the shop (passing the other punches) to use this one. Maybe its bc I paid $50 for it but either way, I like it and will buy at least one more for the shop. Its Starrett, you cant go wrong.

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.

Im a retired tool and die maker of 35 years. I started buying Starret precision tools in the early 70s. Back then those tools were far superior to anything on the market. I still use them to this day which speaks volumes about the quality. The only reason I purchased an auto center punch is because my original punch disappeared about a month ago. My daddy always said Dont buy the cheap tools because in the end it will cost more to keep replacing them than if you spend a little more on quality.

Good hit, heavy duty

A little steep in price but well worth it! This punch will be more reliable and outlast dozens of cheaper foreign made models.

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!

This tool has superior quality and strength. Lots of spring force (adjustable to reduce if you wish). Nice hard tip can mark anything softer than a hard chrome socket. Incredibly useful for scribing as well and center punching.

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.

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.

I live on the Gulf coast in Texas and everything rusts if you dont keep it indoors or slather it in grease. This punch got left outside for almost two months by accident but NO RUST! Thats a big selling point for me. Punch is adjustable but I like deep divots so always use it at max pressure on steel or aluminum. On aluminum it makes a nice ding. On cold-formed steel like a metal building structure its just making an average ding, which was disappointing to me. Admittedly thats work-hardened steel but I did hope it would make a good deep dent. For mild steel the ding is good enough to center a 1/8 bit with one punch, though I usually double or triple punch everything anyway. On aluminum one punch is plenty. It feels too expensive for the difference in performance compared to the $2 HFT punch, and I still find a solid punch and a hammer does far better. However, its more convenient to use an automatic punch particularly in small spaces, plus I already own it, so Ill keep using it. Would I buy it again? Probably not. For reference, I do a lot of metal work but its all for personal enjoyment and not as a tradesman using it for a living.
