Grizzly H2993 Machinist's Square Set, 4-Piece

I'm usually longer winded, but I don't know what else to say -- buy these. The quality against price is an absurd ratio that cannot be competed with. Even factory second sales are wildly more expensive for a set this nice. How square are they? I don't know exactly. But I can tell you that they're at least as square as my Starett combination and double square set. I wish I could recommend these for a machinist, but I simply don't have a mechanism for detecting square at the level a machinist would require/want. My only caution is that these are a bit on the thin side.They're not of the hefty ilk. Not something you want to leave lying around where it could potentially have a force (of some kind) throw it out of square.

This square set isn't going to win any beauty prize but they will get the job done. Package arrived as expected with all the signs of economical manufacturing, squares were all wrapped in plastic with a decent coating of protective oil for transportation. At first I was impressed with what I got for the money , 4 sizes of squares in their own storage case. After unwrapping and cleaning them up I was more of "content" with what I got for the money. First thing I checked was the accuracy of the square against a precision setup block and found that pretty accurate. Material used in them is definitely not a selling point, a couple of the squares have inclusions in them the foundry. Over all they will work for the job intended provided your not measuring high precision parts. Bought as an inexpensive tool for the assembly table in our shop where things can take a beating and was not willing to see an expensive precision square hit the concrete floor. My intent is for these squares to have a life expectancy and then be replaced, most likely with the same ones, so for value I'd say these are a hit.

Was a little surprised at how small these were, but that’s my fault for not fully reading the description. They’re accurate enough for anything I do in my garage workshop and even the smaller ones are good squaring up table/miter saw blades and came in handy when making jewelry boxes for my wife and daughter. I’d guess if you’re into higher end woodworking, furniture making or something that requires high precision accuracy you’d want Starett, but for weekend hobbyists these are pretty darn good.

Woodworking use, still not accurate enough. For machining absolutely, 100% not. None of the 4 squares are actually square, either to each other or reference squares. Some of the surfaces are not flat, as in visually not flat did not bother with gauges. The thick bases as well as the beams, thoug the bases were mostly flat. Some of the surfaces have burrs or have been hit hard enough to mushroom up causing interference. May work as an inexpensive set to "adjust" if you have a machine shop. But if you have the facilities to correct these then you probably don't need or want a cheap set anyway.

A square set. They are great and I believe they are stainless. For under $20, Great Job Grizzly! My Woodpecker square indicates all of the angles are exactly 90 degrees. My Starrett straight-edge indicates everything is flat. No light! Now I can put both of instruments safely away in the cabinet. One interesting item about these squares is that there is not a nominal measurement anywhere to be found. There are no edges that have any multiple of 1/64" or 0.1mm. Grizzly didn't offer measures and it almost appears they went out of their way to deliver! Oh well, I still have expensive calipers and rules for that.

These would be great except for coming with rust on one and another with a bent corner. Too be fair - that could be an exception. I think I waited too long for a return. They are, however, square and great to have in multiple size. A must have tool.

The items arrived in a timely manner. As stated by another reviewer these squares are not stainless steel. It doesn't bother me at all. I just put a light coat of paste wax on them and they won't rust. In fact I prefer they not be stainless so that I can use magnets to hold shop made marking jigs to the squares. I checked them for squareness and they are all OK. I'm not saying they are perfect, but they aren't alleged to be. If I need a square with .0005 TIR over the length of the blade then I will shop for a square with that certification, and expect to pay much more for 1 square than the cost of the price of these 4. Contrary to one reviewers statement, they are not "Toys", and they are pretty dang square. If you are a woodworker as, I am, these will work great. Any amount of run-out they have is less than the amount of wood movement that will occur. If you really need a super precise square, shop for a square that has a guarantee or certification of accuracy.

This is a decent product, but description says stainless. They are not stainless. Once I saw a stainless version I ordered it and didn't look for another. I just don't like getting something not as described. Other than that they are decent squares
