Collection: Expanding Drums

Rubber drums that grip a sanding belt by centrifugal force — no clamps, no glue.

• The angled slots in the rim open as the drum spins, expanding against the belt and locking it in place.
• Belts change in seconds: stop the drum and the belt slides straight off.
• Sizes 6" x 1-1/2", 6" x 2-1/2" and 8" x 3".
• Takes silicon carbide, diamond or cork belts in the matching size.
• The rubber face flexes under pressure, so the belt follows the curve of a cabochon instead of flattening it.
• A drum is a long-life item — you replace belts, not the drum.
