A removable chuck for a drill has a drill bit receiving portion, including a mechanism to receive the drill bit. The drill bit receiving mechanism has an inner member and an outer member rotatable about the inner sleeve to tighten a drill bit into the receiving mechanism. The outer member has a desired length to enable gripping by a substantial portion of a user's hand. A shaft retention mechanism includes a housing directly coupled with the inner member. The housing has an outer surface with the desired length and gripping surface to enable gripping by the user. This gripping surface enables a user to provide a counter force on the housing when a drill bit is tightened in the drill receiving mechanism.
