Abstract
An abrasive article that may include a circular substrate with a plurality of segments arranged on the circumferential surface of the circular substrate. The abrasive article may also include an outlet slot defining an open space on a peripheral portion of the abrasive article between a first segment and a second segment, a center slot defining an open space in the circular substrate connected to the outlet slot, a noise absorbing hole connected to the center slot and protruding from the center slot in the rotating direction of the abrasive article, and a ratio (H+X)/CSD of at least about 0.01, where H represents a prescribed height of the noise absorbing hole, X represents a prescribed depth of the noise absorbing hole and CSD represents the diameter of the circular substrate.

An abrasive article comprising:
- a circular substrate;
- a plurality of segments arranged on the circumferential surface of the circular substrate;
- an outlet slot defining an open space on a peripheral portion of the abrasive article between a first segment and a second segment;
- a center slot defining an open space in the circular substrate connected to the outlet slot, a noise absorbing hole connected to the center slot and protruding from the center slot in the rotating direction of the abrasive article;
- and
- a ratio (H+X)/CSD of at least about 0.02 and not greater than about 0.2, wherein H is equal to a prescribed height of the noise absorbing hole, X is equal to a prescribed depth of the noise absorbing hole and CSD is equal to the diameter of the circular substrate.
