The Mahi Precision Bit Set includes the iFixit 1/4" aluminum bit holder with magnetic bit retention, knurled grip, and rotating cap, along with 48 bits. In addition to standard Phillips and flat bits, this kit contains all the 1/4" bit types you need to tackle even the toughest and most twisted fasteners during repairs at home or in the workshop. The bit sets are designed for maximum utility: to extend the lifespan of the case, the lid of the bit set is secured with magnets, avoiding wear-prone hinges and closures. While working, the lid can be conveniently attached to the back of the case to save space or used as an integrated sorting tray for storing screws and components.
