Square Base Marking Block

A fully hardened and ground base which serves as an accurate reference surface. A machined ’V’ groove in the base allows the gauge to be used conveniently on curved surfaces with ’v’ groove at the front end allows the spindle to adjust to any angle above or below the base allowing it to be used as a height. The two retractable pins allow the gauge to be located against the edge of a surface plate or T-slot for linear work.
