The X431 Standard for Metal provides a good finish when grinding edges and welded seams as well as coarse-sanded metal surfaces. Its semi-friable aluminium oxide grit is robust and wear-resistant, producing a consistent finish. The sturdy backing material is x-cloth: providing stability when grinding for clean and even results. The grit is bonded using fully synthetic resin for wear resistance in heavy-duty applications. The carrier plate is available in both angled and straight, fibreglass and plastic versions. The X431 Standard for Metal is compatible with angle grinders.
