Storage chests for tools or the like feature swiveling drawers pivotally mounted to avoid jamming due to misalignment in use of a sliding drawer. The chests employ unique locking systems tailored for use with such pivoting drawers, where an actuator is operable to pivot a blocking member inside the chest between the drawers and a wall of the surrounding housing about a vertical axis into a position interfering with motion of a feature projecting outward from one or more drawers under attempted pivoting thereof. Some embodiments feature a wheel deployment system operable to give a user control over when to rollably support the chest or have it stand on stationary legs, for example for use of the top surface of the chest as a work surface.
