I bought these for woodworking, after discovering recently that a few of my store-bought squares were not "square". These do appear entirely square — I tested by drawing lines across a board, going both directions, and the two lines matched up perfectly. I don't know whether I'll ever need the two tiny ones, but the two larger ones are now on my work bench and have already been used a few times in the past two days.

I purchased these Boomgood machinist squares not quite sure what the quality would be. Well, I'll cut to the chase and tell you they are fantastic, accurate and an overall solid tool.They come in their own plastic cases for storage and safekeeping. The squares themselves are impressive considering their overall cost. Good solid metal, excellent machining with no burrs. They are truly 90 squares, and super easy to place against a piece of wood or metal to mark for an accurate cut or other measuring. It's generally not easy to get excited about squares, but these are excellent quality at a good price--currently $28.99 here on Amazon.These are such good quality that I will be ordering another set to make sure I have another set in my metal working tool box.If you're looking for a nice set of squares, I would highly recommend these 5-star items.

Did I need them when I bought them? Nope... did I need one a week later? Yup? Are they square? idk? didn't check. Are they square with what I was checking? Yup...Nice set, nice price, wish all hobby machinist tools were this good and affordable.

These arrived and were way beyond my expectation. Heavy but balanced. Quality in every measurable aspect. And sturdy plastic cases.

these precision squares look great. I have not yet use them, but they look very nice and machined well. Will help with my machining projects.

Not Square, square.It's my own fault for buying these squares. I should've known - if it looks too good to be true - it probably is too good to be true. This is absolutely one of those times.These squares are NOT square. One of the four squares was almost square (very very close to square). The others were out quite a bit. The outsides were out on all 4 sizes. The insides were actually much closer than the outsides but not perfect.It's very disappointing overall. I will be returning them. If you want good quality, it's going to cost you. The plastic cases were nice and the squares were nice and heavy but they can't be used for precision work.See pics.Manufacturer MUST do better.
