Abstract
A dental diamond bar comprising a grinding section which has diamond abrasive grains electrodeposited on an outer peripheral surface of a forward end portion of a bar body. A paint-applied section has a colored paint applied to an outer peripheral surface of a part of the bar body. The paint-applied section is located adjacent a rearward edge of the grinding section. In a method of manufacturing the diamond bar, the colored paint is applied to the bar body to form the paint-applied section. Masking liquid is applied to the bar body to form a masking section. The masking section has a forward edge which is located between forward and rearward edges of the paint-applied section. The masking section extends from the paint-applied section toward a rearward end of the bar body. The masking section is removed after formation of the grinding section.
