Description:
Another combination tool, but with a machinist twist-- combined surface gage and marking gage. In this tool, the shaft of the surface gage can be detached from the base to form a wheeled marking gage. Being a machinists' tool, this gage also has a micro-adjust capability to allow fine tuning of the mark.
