3M 782C fibre discs are the ideal choice for grinding carbon steel. Thanks to revolutionary technology – precisely shaped ceramic abrasive grains* – they offer faster material removal and a longer service life than zirconia-alumina products (AZ) and conventional ceramic abrasives. 3M 782C discs also require less pressure than conventional abrasives.
* 3M precision-shaped abrasive grains use 3M microreplication technology to create sharp points that produce less heat when "slicing" metals, grind faster, and last longer than conventional abrasives. These tend to "tear up" metals, which causes increased heating of both the workpiece and the abrasive.
