Provided is a beveling grindstone in which diamond abrasive grains etc. are prevented from falling off even after long-term grinding to allow long-term use of the grindstone and in which chipping that occurs during beveling of a hard and brittle material and the occurrence of cracking in the ground material are suppressed. The beveling grindstone is used to bevel the outer circumferential edge of a hard and brittle material and includes: a core having a groove portion formed on the outer circumferential surface thereof with which the outer circumferential edge of the hard and brittle material is brought into contact; and an abrasive grain layer which is formed in the groove portion and to which abrasive grains are secured by brazing. The abrasive grains have an average grain diameter of #4000 to #270. |
