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

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.

If youre reading this, theres a 95% chance you saw this punch on the Canadian fabricobblers YouTube channel. Like he said, this isnt a necessary tool, but is it ever nice to have. I find that it either takes two strikes with heavy tension to get a good starting mark, or one strike on light tension, followed up with an actual hammer and punch. So, its not a one-hit wonder, but it will definitely let you mark the spot precisely. Its saved me enough time and frustration in the three months Ive owned it that Id say its earned five stars.

First let me thank the Amazon Customer whos 2017 review mentioned that he couldnt turn the knurled adjustment cap. Here it is 2021 and I had the same issue, but with a vise and pliers it opened right up. After a little testing I see a big difference in dimple size between the light and heavy settings. I cant really address durability except that I inherited a Starrett 18A lighter duty model out of my grandfathers toolbox years ago and its still punches just fine. I just thought with this heaver punch I wouldnt have to follow up with a hammer and punch on the harder metals, and so far so good. I keep HF punches in the cars for breaking windows in emergency (and test them every so often), but for real work Starrett cant be beat.

Well made but very expensive. Durability can only be gauged after extensive use.

I figured out that to get the punch to reset after each punch, the rear cap had to be unscrewed almost all the way off. (Yes, Im working with steel.) I currently have the cap taped to the body of the tool so its position doesnt change. The video didnt help. My 20 year old tool started not resetting, which is why I bought a new one. If you fiddle around with the tip after each punch, it sometimes resets. I expected a better tool for the price.

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.

Useful, but a bit stiff in use. Might ease up after a while, but excellent quality. Made in USA!!!

I purchased this item to replace the cheap Chinese units that I have been struggling with for years. The punch is heavy in the hand, and works as advertised. It is easy to adjust the force that the punch strikes with simply by turning the knurled handle on the top of the tool. Replacing or re-grinding the point is easily done by unscrewing the lower portion of the punch. The punch leaves nice deep marks without excessive pressure being put on the tool. If you are looking for a quality tool, Starrett is the way to go. One note about the listing, the 18C that you purchase will be the one pictured on the left of the image above. The tip shown on the right side punch is an add on that is not included.

I have long wanted one of these and was put off by the cost. The reviews on the imports were pretty poor. I have had great luck with all the Starrett tools Ive bought over the years so decided to spend the 2 to 4 times greater cost for the Starrett. I am glad I did as this works very well. I have the heavier duty 18C version and it really hits hard and leaves a good center-punch. I am sure this is a tool that I will pass down to my son.

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.
