Advice on engineer's squares

[Russ Sears]

Do I want these (on sale for $29.74) or these?
Are the cheaper ones, um, cheaper?

[Randal Stevenson]

No matter what you get, check them. I bought the cheaper, Enco ones, based on what an machinist friend of mine said. Found lot's of people that liked them. But my case was damaged and the largest one was visably out of square. I never returned it, since I already had that size, elsewhere, and the set was less then buying them individually.

I have the Groz and can recommend them. I didn't see any accuracy rating on your second link, so I would check that first. If the second set has a higher accuracy, go for it, but otherwise you may want to go the safe route with the groz.

One of the Harbor Freight "jewels" are their engineer squares. Low cost and accurate. Another good alternative is plastic drafting squares. Just as accurate and cheap.

[Joe Petersen]

You already have a recommendation for the Groz. I don't know it myself. Enco usually carries 3 or 4 levels of quality. Enco brand being 3rd or 4th respectively.

[Aaron Dunham]

I have a set from Groz and they are as square as can be.

[Guy Germaine]

I have the Groz set too, and so far, I'm happy with them I checked mine when I got them, and they were dead on.

[Matt Day]

I just talked to Enco about the accuracy levels yesterday and they said that the accuracy for H is .0008, N is .0002, 1 is .0004, and 2 is .0008. She didn't know what the workshop grade was, but agreed it was probably about .001.

I'm not sure if that helps, but I'm not sure which to buy either!

Why are they calling them "engineers"~??

They aren't. Engineers have little or no need of an accurate try square and that's what they are properly called "Try Square"

"A machinist square or engineer's square is the metalworkers' equivalent of a try square."

I just picked up a set of the Groz at Rockler (same price).
Before purchasing them, I asked if I could verify them against a Starrett combination square that they were selling (for $85!!). 2 of the 3 were dead on, but one was a bit off (I held them up to see if light peaked through the space inbetween the Groz and the Starrett).

I then checked a second box of Groz, and they were all dead on, both inside and outside.

I went home, and checked my combination square against the Groz. Needless to say, now I'm on the lookout for a used Starrett square!
