The Mahi Driver Kit includes iFixit's 1/4"" aluminum screwdriver handle with magnetic bit socket, knurled grip, and swivel top-plus 48 driver bits. Spanners, Squares, and Splines-oh my! In addition to standard Phillips and Flathead, this bit kit includes all the 1/4"" form factor bits you'll need to handle the toughest and torque-iest fasteners in any home or shop project. All our next-gen bit kits have been re-engineered for maximum utility. The bit kit lid is held in place with magnets to increase product lifespan (no more broken hinges or clasps) and also mounts to the back of the bit kit case to keep it out of the way while you do your work. Or, if you need help keeping your screws and parts organized, use the lid's integrated sorting tray.
