Perfectly squared. Ideal for setting up the table saw, miter saw or router bit.

### ⭐⭐⭐⭐⭐ Great tool
*by J***. on September 15, 2024*

Very clean, neat and to spec. This can be used to check the perpendicularity of parts and assemblies. I use it make 90 degree starting grooves when cutting aluminum sheet and bars. Doesn't tilt or slip like the thinner ruler of combination squares do. I place a piece of flat stock between the square and the saw. The thicker vertical part of the square is what makes the difference.
