This 00-grade granite right angle ruler is a professional measuring tool used to detect and verify the right angle of mechanical parts. It is made of natural high-density granite, which has the advantages of high hardness, corrosion resistance, and stable performance. Compared with steel right angle rulers, it will not deform due to temperature changes or long-term use, and can maintain long-term measurement accuracy. It is widely used in precision machining, mold processing, and instrument calibration scenarios to solve the problem of inaccurate angle measurement caused by tool deformation.
