The drill bits are connected to the hexagonal shank, and in the set I received they are significantly bent, causing the drill bit to wobble on the tip by as much as 1/2 to 1/4 of an inch.  This renders them unusable.  The packaging looked okay, but I'm not sure if they took a hit that caused them to get bent or if they came that way from the factory.  These may not be eligible for return, but suffice to say I'm disappointed with the product and I may have to try talking to DeWalt, but it's more hassle than if I had tried to find them at Home Depot.
