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

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.

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.

This thing put a nice notch in hardened steel pipe with 0 trouble whatsoever. It will mark whatever you need it to mark. Its strong and clearly well made. Great investment.

Wow... this is powerful. Like other reviewers, I received this with the knurled cap so tight I couldnt budge it until I put it in a vice and rotated it w/ pliers. But even before loosening the tension, I tried it on a piece of hardwood (Teak) and it punched a good hole in it (albeit at the expense of straining both of my hands). After loosening, the tension/punching was much easier to manage. Id buy again - a bit pricey but worth it.

Been using these punches for decades at work. Needed some better punches at home so I went straight for these. Expensive compared the Chinese alternatives but there really is no comparison. If you appreciate nice tools and need a power punch, look no further.

Everything Ive grown to expect from Starrett. Inheriting my grandfathers Starrett mics and running metrology & calibration labs during my career have me a $tarrett believer. Pricy but will be reliable and accurate forever.

No doubt this is the best auto center punch that I have owned. That is, until it stopped working. Lasted about 3 years, but I use it almost every day. This punch is for metal, not wood people. If you need a punch for wood get a Harbor Freight special. It held up to whatever I used it on - Stainless, Mild Steel, Aluminum, etc. and then one day it would not actuate. Tried everything and couldnt get it working again. Emailed Starrett, warranty on these is only a year from purchase, so I reluctantly sent it back for repair. The cost to repair was about $12 shy of buying a new one. Hate to do it, but like I said - this is the best Ive owned.

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.

Finally broke down and bought this one after trying the spring tools punch and the general tools 79. The spring tools punch the spring eventually broke, snapped and hit my finger. The general tools 79 I still use for wood. Only issue I have had when I have it a heavy tension and I am odd angle cannot easily depress it but that is ok.

For some reason, mine wasnt firing properly when I first got it. I was about to return it, but decided to open it up, clean it and put it back together first just to make sure there wasnt something hanging it up. Nothing obvious noted when it was apart, but when I put it back together it worked fine, and has ever since. Oddball issue, but overall Im very happy. This thing is typical Starrett quality - built like a tank.
