Machinist Square Precision Engineer Wide Seat Square 90 Right Angle Ground Hardened Steel Angle Ruler 7.9 x 5 Inch

a great little square built well i highly recommend it

This is the perfect size for making sure my table saw blade is 90 and that my rip fence is 90. I also use it on my bandsaw and my jointer. super glued a small rare earth magnet to the side of the the square to have it handy for use on my table saw.

Small but very good and accurate

I bought this to use woodworking.ATM, I can't recall which one I had to 'adjust' to make it 'square' & I'm away from my shop so can't check.It might've been this one but whichever I had to file 1 edge of the blade to make it 'square' inside AND outside.Anyway, this is a good woodworking square even if I did have to 'square' 1 blade edge.That is not unusual nowadays.I see many amazon reviews where folks buy a square & complain "it ain't square"!Simple, FIX it!FIRST, check it for square, use a factory edge on plywood, checking the inside 1st, strike a line on the plywood.Flip the square over, strike another line close to the first.Both lines are "supposed" to be parallel if the square is really 'square'.If not, figure out which end is off & file HALF the difference off at the end where the 2 lines are closest.That means you file off a *VERY* small amount & use a smooth file.Then CAREFULLY file off the 'curve' you made when you filed the one end, tit it's "straight" & true.Repeat the process with the outside of square & you're done.BE CAREFUL!But it's not too hard & you can be off just a bit & 'get by'.Hopefully helpful.

Perfectly machine, quality product, received in lightning, fast speed.

perfect to check drill press angle or any small tight space needing 90 degrees.

Not even close to square!

Perfect size for making knife scales. I love it.
