Use your iFixit bits (¼ in) with your LTT (Linus Tech Tips) screwdriver (1 in)
This was also designed to fit within the bit holder of the LTT screwdriver so that you carry it with you wherever you go
While the adapter that comes with your iFixit kit for drills does work, the magnet from the ltt driver loses a lot of strength and the bit can sometimes be left behind. With this model, it makes use of the existing magnet, and just helps to center the bit within the pre-existing slot.
