Kinex Precision Try Squares Stainless 75 mm x 50 mm DIN 875.1
These 75 mm x 50 mm precision try squares are made by Kinex to Accuracy Class 1 according to the DIN 875 standard. Their accuracy is several times better than many other high accuracy woodworking squares. They are made from stainless steel and supplied with a foam lined cardboard box.
The blade is 17 mm wide and 6 mm thick. Accuracy Class 1 to DIN 875 is equivalent to a squareness of better than 0.014 mm (0.00055") along the entire length of the square. The high accuracy, small size, and stable base make this square a good choice for checking the squareness of table saw blades.
