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

The Starrett automatic center punch has the same high quality as all other Starrett tools I have ever owned. It is a little stiff to use when adjusted for full impact but creates a nice little punch mark where you want it. I can highly recommend this item.

Works well and the ability to adjust it for your needs is a bonus

Ive a few of the el-cheapos about, which do okay. Wanted one tat would lay a definitive mark with less activations. This does that. At first I thought I may have over done it; s it does take more push. But once used to it, I like it fine. Will likely eventually bore a golf ball to put on the push end to spread the force. Seemed a large piece of money; I have no regrets. Higher quality tools cost a bit more, but by my experience are worth it.

I have used automatic center punches quite extensively for metal work when fabricating industrial control panels. They are a vital tool to drilling precise holes in metal and they offer the convenience of not having to use a hammer. I purchased this starrett punch because of the quality of their other tools and because I have used cheaper ones that would take multiple blows to create a small dent because they just do not have the striking power needed. I also know that when it comes to tools the best ones are a joy to use and the cheap ones will only make you wish you just paid the money and got the best one to start with. I was unsure of which one to order because I could not find any information online comparing the AA, A and C sizes, I ended up purchasing the 18C because it was listed as heavy duty and I figured I could turn down the striking power but if it was not enough on the smaller ones you cannot turn it up. I think for most peoples uses the 18A would be the most ideal size and power. The punch showed up in perfect condition, when held in the hand it does display true craftsmanship and quality which is so hard to find these days. The tip is not quite as sharp as I would have liked for those jobs where you want absolute precision, clearly it is made for heavier duty work than the other punches I have used in the past, and when the spring is turned to its maximum power it does take quite a bit of force to depress and strike a blow but you can be sure that one is enough. I would be mindful that when turned all the way up if you were to push down at any sort of angle you would risk the tip slipping and just putting a huge gouge in your work but sometimes you need that sort of power. When turned down however it delivers a much lighter blow that is even useful for wood, albeit maybe not something like balsam. The machining and quality of this tool is as I said top notch. Yes you can get a punch for just a few dollars that might work just fine but you invest in a tool like this and it will last a lifetime. It is also very easy to take apart to clean or lube if you ever need to. Very pleased with this tool and I wish I could afford to outfit my entire toolbox with tools of this quality.

Highest quality item. But a high level of arm strength needed to operate. Perhaps the design needs an enhanced setting mechanism.

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.

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.

First off-this is a quality product, for professional use. There is no slop on the part fit up, and replacement parts are readily available through the manufacturer. It’s a tad expensive, but it’s worth more than what I paid for it. It’s easily adjustable, and strikes reliably, without losing its pinch pressure setting. A tad stiff at the hardest punching level, I would recommend some type of padding or impact glove for all day use. This tool works very well for pricking holes in 308 stainless for line up on a drill press, or an ironworker (punch).

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.

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.
