An attachment for a power tool (10) has a drive shaft (32) for driving connection to the tool (10) and a rotatable disc (12) linked transversely thereto. The link between the disc (12) and shaft (32) is formed by a flexible membrane (16) which permits relative angular movement between the disc (12) and shaft (32). A locking arrangement (34, 36) is also disclosed which enables the disc (12) to be selectively held substantially rigidly with respect to the shaft (32) if desired. |
