基本信息
This precision granite right angle square is a professional measuring tool designed for detecting squareness and verticality of workpieces, widely used in mechanical processing, mold manufacturing and precision instrument testing scenarios. Made of high-purity natural granite, it has excellent dimensional stability and wear resistance, which can maintain long-term measurement accuracy without frequent calibration. Compared with traditional steel right angle squares, it has no magnetic adsorption, will not interfere with non-ferrous metal or electronic workpiece testing, and has better corrosion resistance to workshop oil stains and dust. It is suitable for high-precision squareness detection of small and medium-sized workpieces in machining workshops.
