A rotary tool includes a housing defining at least one slot and a motor including an output shaft supported within the housing. A collet chuck is coupled to the output shaft that is configured to slidably receive a collet. The collet chuck includes at least one lever arm configured to apply a clamping force to the collet. A wedge is configured to move into and out of engagement with the at least one lever arm to generate the clamping force. A bearing is attached to the wedge, and a yoke member is attached to the bearing. The yoke member includes at least one lever structure that projects outwardly from the yoke member through the slot in the housing.

Release mechanism for a rotary tool

An accessory tool retention assembly for a rotary tool includes a collet having a body defining a collet axis and having a plurality of flexible segments that extend longitudinal along the body generally parallel to the collet axis, each flexible segment including a curved end portion that curves radially outwardly from the collet body. A collet chuck is configured to be coupled to an output shaft of a motor of a rotary tool. The collet chuck defines a collet receiving passage configured to slidably receive the collet. A front wall portion on the collet chuck defines an insertion opening aligned with the passage of the collet chuck. The front wall portion defines a plurality of recesses sized and shaped complementary to the curved end portions of the collet. The plurality of recesses is positioned to receive the curved end portions when the collet is inserted into the collet receiving passage.

Collet positioning mechanism for a rotary tool

An accessory tool retention assembly for a rotary tool includes a collet having a body defining a collet axis and a plurality of flexible segments that extend longitudinal along the body generally parallel to the collet axis. Each flexible segment includes a curved end portion that curves radially outwardly from the collet body. A collet chuck is configured to be coupled to an output shaft of a motor of a rotary tool. The collet chuck defines a collet receiving passage configured to slidably receive the collet. A detent structure is positioned to block the collet from exiting the collet receiving passage while the flexible segments of the collet are in a relaxed state.
