It has held up extremely well and cuts just about most kind of rock, from the very soft petoskey stone fossils to hard jasper, petrified wood, geodes. We don't recommend using the 14 inch lapidary slab saw to cut too hard materials, such as: agate with a morse hardness of 6-7. Because it is difficult to cut or the saw blade will be damaged quickly. A high concentration diamonds are crimped into the blade rim. More diamonds in the notched rim and a stiffer core make the lapidary blade cut faster and provide a long use-life. The 14 inch lapidary blade work well with most lapidary materials and are a very affordable alternative to name brand blades. New, Unused Blade - Not in Original Packaging The 14 inch lapidary saw blade is originally packaged in oil so you will see several oil spots on the surface.
