    Description

    Product description

    This WanHu mandrel mounting hardware kit is built up from layers of steel cloth. It is part of the WanHu buffing wheel range, which covers diameters from 75mm to 250mm in several ply counts, colours and centre types so you can match the wheel to your machine and to the finish you need.

    Uses

    Used to mount cloth and buffing wheels on a bench grinder, polishing lathe or drill. Fit the flanges either side of the wheel and tighten by hand, then let the machine torque pull it up — overtightening crushes the cloth.

    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.

    Spec code format: diameter (inch) × ply count — 4 × 50, 5 × 50, 6 × 50, 7 × 50, 8 × 50, where 50 ply means 50 cotton layers. Finished thickness is 12 mm across the whole range.
