    Description

    Product description

    This WanHu buffing wheel is made from natural pig bristle. Part of the Buffing Wheel range, it comes in several colours and sizes so you can match it to your machine and finish requirement.

    Uses

    Suitable for cleaning, deburring and polishing metal, jewellery, moulds and woodwork. Mount the buffing wheel at moderate speed and let the bristles do the work — excess pressure shortens service life.

    Safe Operating Speed

    A bigger wheel must run slower. The limit is set by peripheral speed (how fast the rim travels), not by a fixed RPM number — so the safe RPM drops as the diameter grows.
