Abstract

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.
