For universal grinding work on components made from aluminum, copper, bronze, titanium and fiber-reinforced plastics. Excellent for use on titanium alloys. Ideal for the aeronautical industry, especially where SiC is the only approved abrasive, e.g. for use on engine components. RS type COMBIDISC® abrasive discs are ideal for weld dressing of backwards repair welds, e.g. in cases, slots and grooves on engines and for processing welded-on combustor plates. Unlike on conventional abrasive discs, the abrasive coating is on the underside of the tool, which allows backwards working.
