Norton 57A Centerless Wheels are made using strong, blocky-shaped aluminum oxide in a vitrified bond. This versatile/durable abrasive is well suited for general purpose applications, featuring high “G” ratios (metal removed/wheel wear). The superior vitrified bond system offers longer wheel life, with excellent form holding.
