Pearl quality is more than innovative design - it is advanced engineering and rigid quality control. Pearl's revolutionary SRT grain makes this grinding wheel last longer than the competition, while providing significantly faster grinding performance.
Pearl's depressed center grinding wheels are especially well suited for grinding, weld dressing and deburring. Pearl depressed center wheels are engineered for aggressive stock removal and extra long life. All wheels are fully reinforced and meet or exceed US/Canada safety standards and specifications.
