Steelwool is produced in many different forms to better suit many types of applications. Steelwool is available in 8 different levels of abrasiveness or “Grades”. The grade is determined by the thickness of the wire of which the wool is made of. We control the wire thickness when shaving the wool from rod by selecting the right type of serrated tools. The more serrations on a tool will yield a finer wire or shaving, while less serrations will yield a coarser wire or steel wool.
