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

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!

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

Product quickly arrived as promised. This small punch makes a tiiiiiny indention, enough for a drillbit to lead. I do wish was more potent and made a larger indention in sheet metal.

After just a few uses, stopped resetting after punch. Springs seemed to be worn even when new. Internal pin seemed to wedge in body. Could be a knock-off and not a real Starett.

After yet another Harbor Freight punch wore out, I decided to buy a real tool. The Starrett auto punch is definitely well made and feels good to hold, and operates smoothly -- but it doesnt do much. Im getting just a tiny nick in 24ga steel sheet metal, and not much better in 1/8 aluminum extrusions. This is at the highest setting. I guess this punch is only really intended for softer materials, but that wasnt super clear to me in the description. Im just a weekend warrior and not familiar with the intricacies of selecting proper fabrication tools. Evidently I I was also surprised by how small it is...the dimensions are clearly given but I have small hands so figured it wouldnt be an issue. I can hold it fine but it gets lost in the pencil-loop of my toolbelt where I kept my old one -- I have to take off my gloves and poke around in there to fish it out, which isnt much of a time-savings. Im returning the punch in favor of the full-sized 18C, which apparently is more like what Im looking for.

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.

Commercial hollow metal door layout and prep

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.

This punch is small, which is a plus, and very dependable. I use it anytime I want a small centering hole. Just push and punch. Well worth getting. The self tapping feature is easy and reliable. Dont know why it took me so long to find this device. No more hammering. Now a simple one-handed operation. Listen for the click and you know you have a made small centering mark.

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