Metal polishing with discs can result in swirl patterns which may or may not be desirable. Polishing to a mirror finish (completing all stages) should avoid this. Polishing discs should thus be considered in the context of an overall process, depending on the start state and required finish of the metal. Trizact, unitised and felt discs may all be used as a combined process. We make this quicker by having all of available in grip disc form.
