These squares are made from a solid block of granite that has been carefully machined to ensure accurate right angles. Black granite squares are more durable than pink granite and help to avoid scratching. Granite precision squares come with one large face and two edges that are finished flat and square to each other. It consists of two faces precisely perpendicular to each other, forming a 90-degree angle. A precision granite square is a tool used specifically for checking the squareness (90-degree angle) between two surfaces or edges. Check 90 degree squareness of the X and Y axes when used in it's horizontal position. Check perpendicularity of the Z axes when used in it's vertical position. Precision granite squares are commonly used with other measurement tools to verify the squareness of various components and assemblies. They are particularly useful in applications where high accuracy and reliability in squareness measurements are required, such as in precision machining and tooling. Square has a round hole so it weighs less and is easier to handle. An inspection certificate from the manufacturer is provided.

Checked using two different Starrett steel toolmaker’s squares on a grade A granite surface plate. The two Starrett squares are blackout square to each other.Neither face is very square to the edges, despite what the product description says (see photos).The two edges are closer in square to each other, but light still shows through (see photo).For the price and the product description, I expected the squareness result I’m seeing for the two edges, but I expected a similar result between the edges and one of the faces.Also, when placed upright on an edge on the surface plate, the square rocks ever so slightly, so the edges do not appear to be all that flat either.I know you get what you pay for, but I expected a better match to the product description (and the inspection paperwork) between the edges and one of the faces.

This is accurate enough for this hobby machinist. It helped me tram my mill to the standards I needed.

I was not visible so they delivered it to my neighbour. Porch Pirate prevention. Thank-you, the product is excellent and in a handy shinny carrying case.

Not bad for the price. Would be nice if it had the calibration cert in description. It is the perfect size. Would bye again.

The first thing you do is have the square checked for accuracy on a granite plate or CMM, Order a Pelican box for transport and get rid of the cheap box the square is protected by. Its really junk.
