PEC 90 Degree 12" Combination Square No-picture-s No-picture-s Click the pictures to enlarge them

This is a review for a combination square that is priced a lot lower than a Starret square, is actually square, and is made in the USA. All good things, right?

-It is square. Really square. All the way along the length of the ruler.
-It slides well. Not AMAZING, but well.
-Fit and finish are pretty decent, but not amazing. There are some sharp corners.
-The graduations are well marked, and very easy to read. (Etched in, I think)
-It came with some anti-corrosion coating on it and had no rust.
-Knurled knob is very easy to grip with two fingers and turn.
-Scratch awl is fine. (although I don’t use it, really)
-I’ve used it for several months, so I think I have a good feel for it and can write a decent review.

I bought it for about $20 on Ebay, not including S&H.

Overall, I’d buy this square again and again, since I have no need for the PERFECT tolerance of a Starret, nor do I have the money to buy one, but I do want a square that is SQUARE and affordable! I also like supporting US companies when possible. This tool fits the bill on all counts.

Disclaimer: I am not a machinist or a tool specialist, nor do It have any way to measure exactly how many thousandths of an inch it is accurate to, but I know that when I cut a line with a marking knife, flip the square and check, it looks perfect!

Thanks for the review. I have the PEC 6” double square and like it a lot.

I didn’t know the 12” combo square could be had so cheaply. I usually would buy from Taylor Toolworks on ebay. Is that where you got yours?

Might have to take a look, the Empire from H.D. getting a little sloppy.
I do have a Starrett but I only use it for important stuff and to check
other squares! The square I use most of the time is a 2 1/2” Lufkin.

Checked E-Bay ca. $42 + 20 for shipping Canadian $

Cache out Harry Epstein for PEC blemishes.
They get good reviews and are very reasonably priced.

Looks like the seller is Reddottool.

I also like buying from Taylor Tool Works.

Thanks for the review. I have a Starrett comb square and use it only for special jobs and for checking other squares. I was able to check a Stanley square against the Starrett and found it to be very much off. I was able to correct this with a little machining, but it is still not perfect. I think I will get a PEC CS for everyday use and send the Stanley to the “framing” toolbox where it belongs.

I have one of these squares, and it’s great. Perfectly square, or at least as perfectly square as my eyes can see, and the fit and finish is very good.

I also have two PEC 4” double squares and a try square. All are great.

$28 for a high quality US made combo square is a good deal, that’s cheaper than the PEC blems.
