For universal applications from coarse to fine grinding, with a high stock removal rate and long service life.
RS type COMBIDISC abrasive discs are outstandingly well suited for weld dressing of backwardsrepair welds, e.g. in cases, slots and grooves on engines and for processing welded-oncombustor plates. Unlike on conventional abrasive discs, the abrasive coating is on the undersideof the tool, which allows backwards working.
