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

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.

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.

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.

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’ve already set over 1000 center marks in 6061 aluminum. This punch is fantastic. Very happy with this purchase.

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)

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.

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

Starrett is one of the great names in American precision measuring and tooling products, and this Automatic Center Punch is no exception. A few years ago, they changed the design of the center punches where the shank and the tip are unitized, meaning you have many more opportunities to sharpen the tip before you require a replacement. Its not as elegant as the original design, but it is more robust, and has one less part to worry about(the replaceable tip) I now have the 18C, and have the original 18A and 18AA. This is by far the heaviest duty unit of the three, and will likely get the most use. It is adjustable, however, even the lightest setting is still quite hard, so if you are working with soft metals or thin gauge stock, you will likely want to use the 18A or 18AA. This one is perfect for my use, and I will now be selling off my General automatic center punch, which takes significantly more pressure to activate and doesnt hit nearly as hard.

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.
