Machinist Square Set, 2" 4" and 6", iGaging 

Set of three engineer's squares, sizes 2", 4", and 6". This set is ideal for set-up work with machine tools, table saw blades, and many other shop tools.

The surfaces and edges are ground for high tolerances of straightness and squareness.

Squares are accurate on both inside and outside angles and meet German DIN standard 875, Grade 1.

Length of blade is measured from inner edge of beam to end of blade. The small notch at the inside corner prevents small particles from accumulating at the juncture and impacting the squares reading.

Typical use involves aligning the beam along one edge of an object with the blade across the body of the work. Using a strong light source behind the square will reveal any gaps showing the squareness of the work.
