摘要： An abrasive article can include a body including a first portion coupled to a second portion in a radial plane. The body can include a central opening extending in an axial direction of the body through the first portion and through the second portion. The central opening can include a circumferential surface defining an inner diameter of the body. The circumferential surface can be defined by at least a portion of the first portion and at least a portion of the second portion. The first portion can include first abrasive particles contained within a first bond material, including an inorganic material, and the second portion can include second abrasive particles contained within a second bond material, including an organic material. The organic material can include epoxy. In an embodiment, the second portion comprises an elongation-at-fracture of less than 2.7%, a Stiffness Value of at least 8.3, or a combination thereof.
