The Manta Driver Kit includes iFixit's 1/4 in. Drive and 4 mm Drive premium aluminum screwdriver handles with magnetic bit sockets, knurled grips, and swivel tops-plus 112 precision driver bits. This kit includes our widest assortment of bits, complete with every driver head you'll need to tackle any repair or DIY project. It includes standard bits like Phillips and Flathead in a full range of sizes to handle everything from precision electronics repair to home DIY projects. And it wouldn't be an iFixit bit kit if it didn't include all the exotic bits from Pentalobes for Apple iPhone and MacBook repair to Gamebits for your vintage Nintendo consoles. 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. And our 4 mm bits have been redesigned with a longer neck for a deeper and more precise reach.
