Abstract

A rotary dental tool. The tool comprises a blank having a shaft portion and a head portion. A single layer of grit comprising diamond crystals extends from the blank at substantially uniform height, said grit covering a predetermined proportion of the surface area of the head portion. A bonding material substantially surrounds the diamond crystals, forming micro-channels between the diamond crystals. The diamond crystal size is substantially less than other rapid cutting tools yet outperforms other tools in cutting speed, durability and smoothness of finish. The micro-channels are believed to both cool the dental tool and facilitate debris removal during use.
