Abstract: An angle attachment for a rotary power tool includes a first assembly including a first shaft and a first gear and a second assembly including a second shaft and a second gear. The second gear engages the first gear and the central longitudinal axis of the second shaft is not collinear or parallel to the central longitudinal axis of the first shaft. The angle attachment further includes a member configured for removable coupling to a motor shaft of a rotary power tool and for removable coupling with the first assembly. At least a portion of the member is configured for insertion into a component of the first assembly.

Abstract: A gear reducing collet nut assembly is provided for holding a tool bit. The assembly includes an outer grip sleeve that can be rotated to actuate a clamping structure with a bore for holding a tool bit. More specifically, the assembly includes a planetary gear system to amplify torque from the grip sleeve to facilitate effective manual operation. The assembly includes a base member that is securable to a shaft of a rotary power tool, and the planetary gears are rotatably mounted at a plurality of positions on the base member. The planetary gears are driven by a central sun gear that is fixed to the grip sleeve. The planetary gears deliver torque to a ring gear that extends peripherally around the planetary gears. Movement of the ring gear is effective to actuate the clamping structure. In an embodiment, an exterior of the ring gear is threaded to the base member and axially fixed relative to the grip sleeve.
