<p>A rotary tool (10) includes a housing (14) defining at least one slot (268) and a motor (24) including an output shaft (84) supported within the housing (14). A collet chuck (108) is coupled to the output shaft (34) that is configured to slidably receive a collet (104). The collet chuck (108) includes at least one lever arm (170) configured to apply a clamping force to the collet (104). A wedge (110) is configured to move into and out of engagement with the at least one lever arm (170) to generate the clamping force. A bearing (232) is attached to the wedge (110), and a yoke member (230) is attached to the bearing (232). The yoke member (230) includes at least one lever structure (252) that projects outwardly from the yoke member (230) through the slot (268) in the housing (14).</p> |
