This isn't a Starrett. So what's new? For the money, my kit came as accurate and functional as possible. The 4" square tended to stick after tightening the knurled nut. On my machine this was corrected by removing the pin and gently sanding the recess to remove milling marks (which would not have been necessary on a Starrett). Lubrication of the parts, preferably graphite, kept the tool running smoothly. All in all only a few minutes of work for a useful tool.
