This kit includes a 4 mm aluminum screwdriver handle with magnetic bit socket, knurled grip, and swivel top-plus 64 precision driver bits and a flexible extension. This driver kit includes standard, security, and specialty driver bits for a wide range of regular and exotic repairs. Standard bits like Phillips and Flathead will get you into most small household appliances and electronic devices. And security and exotic bits like pentalobes will let you gain access to your Apple devices like iPhones and MacBooks. Whether you're a professional fixer or a weekend warrior, this bit kit has what you need to disassemble, repair, and reassemble smartphones, game consoles, wearables, laptops, desktops, tablets, small appliances, and much more! 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. And the 4 mm bits have been redesigned with a longer neck for a deeper and more precise reach.
