Review on Tools Combination Square Metal Body 1794469 by Lori Aguirre

The combined square is very convenient for marking, but I would like to use it as a square itself, which has exact angles of 90 and 45 degrees. But they are not always there. I use the Kapro magnetic combination square, which I wrote about earlier. There is no right angle there, finishing the sole with a needle file did not give a 100% result: the deviations decreased to 10-15 ', but I cannot use Kapro as a square. Accidentally saw on sale squares Empire made in the USA. Few reviews, but no bad reviews. I decided to take a chance and buy a second combined square for the workshop. I purchased a square with a ruler length of 400 mm. There are models of 150 mm and 300 mm. Measurements with a mechanical goniometer with a vernier showed that the angle of 90 degrees and 45 degrees are accurate! The 2 mm thick ruler has a smooth surface and precise markings made by milling, it is firmly clamped in the sole. At the bottom of the sole is a bubble level. Even lower is a long marking needle. The designation IM in the name of the square means that the ruler has two scales - inch (imperial) and metric. There are Empire squares only with a metric scale. The disadvantages include the fact that the ends of the ruler do not look polished or insufficiently polished, while remaining even - measuring flatness using a curved ruler and a probe gives values no worse than 0.02 mm (I don’t have thinner probes). In comparison, Starrett squares with a ruler only 150 mm long, where everything is polished to a shine, cost 5 times more. In general, on the second attempt, I managed to get a good tool ...
