CARBATEC 300 x 230 x 50mm Black Granite Surface Plate GSP-1

This Black Granite Surface Plate provides an accurate reference plate to measure objects for flatness and squareness. It's perfect for lapping tools and checking set-ups on small engineering projects. Affixing wet and dry paper to the surface enables the plate to be used as a large sharpening stone. Each plate is supplied with its own surface flatness test report and is packed in a wooden shipping case for safe transport and storage.
