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

This is a quality tool, yes a bit more expensive than its counterparts, but its the only one you will buy in your lifetime. Unless you are like me and must have the 18a as well BAM! This tool hits with significant force, enough to mark stainless steel billet. Im getting the 18a as well for some lighter sheet metal work. You dont find quality like this often. Im really proud to own this tool. No regerts :)

I use it at work

This thing is ridiculous. It is by far the biggest and strongest center punch Ive ever used. Its about the same size as the el cheapo center punch from ace hardware, maybe a little bigger, but has a much thicker punch and a far stronger spring. You can partially unscrew the tailcap to have a softer punch and at the softest I can make it without the tailcap popping off, it is still stronger than the el cheapo, plus it works every time as opposed to ~25% of the time. On max strength, it punched itself far enough into wood to lodge itself sideways. It punched a sizeable dent in a solid brass block. It punched a noticeable divot in a hardened steel safety plate designed to stop you from drilling. I considered returning this not because its a poor product but because its too damn powerful and I was gonna buy a smaller one! (I didnt)

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.

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 have used both the 18C and the 818 automatic punches and I prefer the 818 in my tool pouch and the 18C on the work bench. The 18C is a workhorse that can be counted on to punch a clear impression on just about any material. Because of the added weight of the 18C, I feel that it provides more comfort in terms of kick-back than the 818 and is better suited to situations where repetitive use is needed. The redesigned tip is an improvement. I had an older one on a previous job that had a screw-in tip that always came loose at the worst time. The tip and shaft form a single unit on this model. The tip can still be replaced if you would rather not resharpen and reharden your old one as it wears down.

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.

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.

If you appreciate quality tools you just cant go wrong when buying a Starrett tool. When you need to mark out placement for a hole to be drilled these make it a snap. Position the tip where you need to drill your hole and give the tool a quick push till it pops and youre done. But, dont be a doofus and hit it with a hammer and then do use a center punch and a hammer to give your drill bit a good solid starting point. This tool is only meant to mark placement for a hole and is not meant to replace a center punch. Use this fine Starrett tool properly and its most likely gonna still be workin the same as when it first came outta its box every time you use it.

Well made, reliable, very strong. With the adjustment nut screwed in fully, it takes a great deal of pressure to pop. Since I keep it in the car to break a window in an emergency, I replaced the spring with a slightly softer one, so it works with less pressure but is still strong. Also it could be used as kubotan if necessary. Tip: If you keep it in the car, or near machinery where there is vibration, the handle may come unscrewed and spray parts hither and thither. So tighten it up securely.
