Sometimes when I drill, the bit spins briefly in the chuck, creating a ringlike burr on the shank, which becomes a problem for bits stored in metal storage cases. As I put the bit away, the burr often hangs up in the tight metal holes of the case, sometimes cutting my finger or causing the case of bits to spill. The same happens when I try to remove the bit from the case. To avoid this frustration, I turn the bits over so the smooth shank sticks out. Now I can remove and replace bits without hangups, and view the solid shank, making it easier to select the correct bit size.
