A Machinist Square with a Wide Base is a precision tool specifically designed for the needs of machinists,metalworkers, and engineers who require accurate right-angle measurement and marking in their work. The widebase adds stability and makes it particularly well-suited for use on large or heavy workpieces, providing areliable reference for ensuring squareness and alignment.
Din 875 Grade 2, which is the normal standard for a decent workshop squares. A grade 2 square has always beenrecognised as being quite sufficient for normal workshop use.
