The SGDQ6 isn't something that should be found in many mechanic's Snap On boxes...rather it can take the place of a dozen screwdrivers in your portable tool bag, under your motorcycle seat, any place you can't fit a dozen screwdriver this kit does the job. The diamond dust coated tips grip like crazy..and the assortment of flat, phillips, and torx bits cover the majority of fasteners that present themselves.
