Abstract
A handpiece for a rotary tool including a flexible power shaft configured for connection at one end to the rotary tool, and at the other end to the handpiece, with at least one locking formation affixed to the shaft. The handpiece includes a housing having a first end for receiving the shaft, and a second end configured for accommodating a working attachment, the housing defining a central throughbore for rotatably receiving the shaft. At least one locking actuator is disposed in the housing for releasable engagement with the locking formation, the handpiece being provided with a biasing force for biasing the actuator out of engagement with the locking formation, so that a user-applied force on the actuator overcomes the biasing force to enable locking engagement between the actuator and the locking formation. A working end of the handpiece housing has an endcap and is also configured for receiving supplemental attachments.
