Cheetah discs are 5" in diameter and you can choose 1/2" or 1" thick discs, depending on the size of your job. These are heavy duty and built to last!  They replace traditional metal or resin bond diamonds.  All you need is water. Their aggressive design allows water and slurry to travel through channels, which improves the quality of the cut.  They are excellent for concrete, terrazzo, granite.  Cheetah discs work well on all limestone, marble, and travertine surfaces as well.
