<p>An accessory tool retention assembly (100) for a rotary tool (10) includes a collet (104) having a body defining a collet axis (P) and having a plurality of flexible segments (130) that extend longitudinal along the body generally parallel to the collet axis (P), each flexible segment (130) including a curved end portion (138) that curves radially outwardly from the collet body. A collet chuck (108) is configured to be coupled to an output shaft (34) of a motor (24) of a rotary tool (10). The collet chuck (108) defines a collet receiving passage (162) configured to slidably receive the collet (104). A front wall portion on the collet chuck (108) defines an insertion opening (166)aligned with the passage (162) of the collet chuck (108). The front wall portion defines a plurality of recesses sized and shaped complementary to the curved end portions (138) of the collet (104). The plurality of recesses is positioned to receive the curved end portions (138) when the collet (104) is inserted into the collet receiving passage (162).</p> |
