Already had a set of security bits but they are much shorter. Given the type of equipment you disassemble, many of them have long recessed holes that require a very long nozzle. These beats work great. I particularly like that some of the smaller bits have a thinner shank than others, making it easier to access the screw head when it's countersunk. I have uploaded some customer pictures to give more details on what exactly you are getting.
