Precision Granite Tri Square Ruler
Striving ahead of the regular industry trends, we strive to produce high quality precision granite triangular square. Using finest Jinan black granite as the raw material, the precision granite triangular square is ideally used to check out the three coordinates (i.e. X, Y and Z axis) of a spectrum data of machined components. The function of Granite Tri Square Ruler is similar with Granite Square Ruler. It can assist the machine tool and machinery manufacturing user to perform right angle inspection and scribing on parts/workpieces and measure the perpendicular of the parts.
