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

Commercial hollow metal door layout and prep

High quality. You get what you pay for.

Good for woodworking, even on softer woods. Sometimes takes a couple punches to make the size of hole that I want but given how easy it is to use this isnt really a con, just press up and down a couple times. It works on metal too but obviously if you are primarily doing metal working this probably wont be heavy duty enough.

Pay attention to the recent reviews regarding failure to reset after triggering, which it mostly doesn’t do. Unfortunately I waited too long before I realized how bad it was. Test immediately, if you bother at all. Apparently, Starrett isn’t the company it used to be. I have vintage tools that are 50 years old and work perfectly, but now there’s a 30-day return limit? Ridiculous! Also, this model is TINY! I didn’t realize a micro-version was an option. Fool me once…

Read the bad reviews. These things seem to have some manufacturing issues. Specifically, the spring over the point seems a bit weak and the things arrive internally dirty with a poor internal finish on parts that slide. However, its easily repairable and just using the unit to break it in will help a lot. Heres how to get it going again. Unscrew the point end and carefully remove the pin, spring and point. Make sure to notice how things are laid out. Clean each component, remove any debris, clean the threads, Use a good lubricant on everything. I like using a dry Teflon type that wont attract dust and dirt. Next, unscrew the top. Careful as there is a spring in there. Now you have to remove the slid inside the top half. Just push it out the top. I used a can of compressed air to blow it out, but a small paper clip would also work I believe. Clean it and the tube. Q-tips are your friend here. Lubricate as above and reassemble. And use it. Wear it in. Youll have to play with the point end adjustment a little, just unscrew half a turn and put back. Itll get smoother and more reliable. Note that on the point end, the point drops in first, then the pin (flat side toward point) and the spring goes on the pin. The smaller end of the spring goes onto the pin first.

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

Starrett is known for making quality tools and this one is no exception. I have already used it for several projects and it has performed well and is still in great condition. Worth the money in my opinion. Would both recommend and purchase again if needed.

I wish it was smaller so I could carry in my pocket comfortably. I could not find a smaller version when I ordered, but this one works great.

I had to return this for a replacement. Half the time, the spring would not rest after triggering. The replacement (same make/model) is great -- heavy, precise, and reliable.

This gets a solid five stars because it really is perfect. The wind up is very, very smooth with a nice and short throw, which helps keep it on the spot while pressing on it. The resulting action is quick, firm, and surprisingly powerful considering how effortless the wind up is. It makes me wonder if they are somehow cheating the conservation of momentum and energy... Oh yeah and the knurling and overall look is second to none. It feels super sweet to hold! Given all of this, plus the fact that it only costs as much as 6 lattes, plus the fact that its still made in the USA, dont even bother to waste your money on a cheaper import (which are only cheaper by about 1/2 as much - were still in the impulse dollars range here folks...).
