The X-LOCK fibre disc R444 Expert for Metal creates an impressive surface finish on metal surfaces. The stable carrier plate made of vulcanised fibre enables an even sanding process. The aluminium oxide grit is particularly suitable for working on metal. This fibre disc is designed for deburring and preparing welding work on carbon steel, mild steel, non-ferrous metals and cast iron. It is also ideal for removing discolouration, deposits and surface imperfections. X-LOCK grinding wheels also fit standard angle grinders. Thanks to the keyless X-LOCK system, the fibre discs can be changed quickly and conveniently. The discs are suitable for mounting on an X-LOCK or standard rubber backing pad.
