基本信息
This 00-grade granite try square is a high-precision right-angle measuring tool made of refined Jinan Qing granite, mainly used to detect the right angle of workpieces, align processing tools and verify the perpendicularity of mechanical components. It has the characteristics of high hardness, wear resistance, no magnetic, stable performance, will not rust or deform over time, making up for the defects of traditional steel right-angle squares that are easy to corrode and lose accuracy. It is widely used in hardware processing, mold manufacturing and mechanical maintenance scenarios.
