diamond circular saw blade

A Diamond Saw Blade is a saw blade that is manufactured with a metal or steel core, as well as diamond crystals adhered to the cutting portion (segments) of the blade. These blades are capable of cutting through extremely hard or abrasive materials, such as concrete, stone, brick, asphalt, masonry, porcelain, tile, granite, marble, and more.  The blade is capable of cutting through hard materials due to the fact that the cutting segments of the blade are composed of crystals. In fact, the blades don't actually cut through these materials, but rather the diamond covered cutting teeth or segments grind through the material to create the cut.
