Granite Block Master
Available with 5 finished sides or 6 finished sides. Granite block masters are necessary for accurately measuring the perpendicularity, squareness and straightness of the X, Y, and Z axes of machine tools.
The granite master squares Fortune provided are made of Jinan black granite,which is stronger and denser than light colored granite, making them more stable and durable. Black granite has a uniformly fine texture and tight porosity, which make it extremely resistant to water absorption or warping from humidity.
