Starrett Automatic Center Punch with Hardened Steel Metal - 100mm Length, 11mm Punch Diameter Tapered Point - 18AA

The punch was as seller indicated and in fine condition, however, not knowing the the model number it was much smaller than the one I had previously owned (US made by General Tool) and turned out to be too small and too light-duty for my purposes... it was like a mini-punch. I had to re-purchase the18A model from another source. I should contact the seller to request a return.

This punch is super high quality, I’ve had it a few months and still working great. But I would say it’s not the best for hard metals, which is what I bought it for. If you are using for marking wood & soft metals (aluminum, brass) should be fine but not so much on steel. I would recommend getting the heavy duty version for about $10 more.

High quality center punch, USA made, type of tool that will last generations

As presented! This punch actually allows one to vary the indentation force via the adjustment knob - unlike a previous purchase!

I use this to punch/stamp date codes into metal castings and I typically have to do it multiple times in the same spot for it to be deep enough for QA purposes (by deep enough, I mean visible without a magnifying glass and/or light to notice the difference). The tool came fully tightened, so theres no way to make the punch hit harder unless I use a hammer (which is impractical in some cases). Maybe the spring is faulty and thats my issue? I dont know as Im not going to try to open it up and risk not having it work even at this level. The tip has retained its point after multiple uses, so thats a definite plus. I would have given this 5 stars if I didnt have to punch the same spot multiple times to see an effect.

It arrived early and workswell. The adjustable punch is great depending on the material youre trying to mark and the size if impression.

This, the 18AA is a little brother to the 18A. Keep in mind that the 18AA has no replaceable tips which can be a good thing as its more rugged. I use auto center punches for aviation rivet removal so they are heavily abused. Starrett auto center punches have never misfired even once for me. Bypass the red punches from the tool truck they are junk compared to a Starrett!

Ok for soft metals, needs stronger spring for most steels

It is smaller than I expected. It works well but I wish I would have gotten the 18c. It would have been a little bit bigger and punched a little bit harder. All in all a very high-quality product!

High quality. You get what you pay for.
