摘要： An abrasive article is disclosed and can include a core and a plurality of identical segments extending from the core. The segments can be arranged on the core to form first abrasive article indicia on a first side of the abrasive article and second abrasive article indicia on a second side of the abrasive article opposite the first side. The first abrasive article indicia can be identical to the second abrasive article indicia. Moreover, the first abrasive article indicia can be offset with respect to the second abrasive article indicia.

摘要： A vitrified superabrasive product includes a superabrasive component and a vitrified bond component in which the superabrasive component is dispersed. The vitrified bond includes an oxide of a lanthanoid. Additionally, the vitrified bond component defines pores that can be essentially all less than 800 μm in diameter. Seventy percent of the pores are in a range of between about 40 μm and about 500 μm and have an average aspect ratio less than about 2. The porosity is in a range of between about 50% and about 90% of the total volume of the superabrasive product.
