Diamond blades are best for cutting tough stones such as marble and granite for interior decor and construction. Since the stone-age man has known the value of stone at home. Ancient man was closer to stone because it was used due to its availability and also because it was a robust and readily available material to build homes. Stone ware and stone utensils have also been discovered in excavations in various parts of India and the subcontinent, where life supposedly evolved.

Even today, stone is often used for fireplaces, hearths, and decorative walls in homes. Stone walls and fireplaces are easier to clean and look attractive. To put these stones together in walls and other interior décor they have to be cut to size first. Since the stones are hard, a very hard diamond blade is used to cut these. These are used on a wet tile saw. A water pump in the tile saw helps keep the blade cool so the job gets done with speed.

It is a circular saw blade used for cutting hard or abrasive materials. For cutting concrete, brick, block, stone and other similar materials, diamond blades perform the best. It consists of a steel core and powder metal combined with diamond crystals which is heated and pressed into a molding to become the diamond segments, which are the actual cutting teeth of the blade. These diamond segments are then welded to the steel core. Another way of making a diamond blade includes electroplating diamond crystal directly to the metal core. Single layer diamond blades are made by a method called brazing (soldering).

The steel core of a diamond blade may be different one from another because of its usage. The spaces called segments are used in the blade to provide cooling. The continuous rim ones are more used for smooth chip-free cutting.
