Almost all common screwdrivers are included in this mini screwdriver kit. If just repairing cell phone, laptop, computer, ring doorbell, eyeglasses, you only need 5-10 of bits and that's perfectly adequate. In fact, most bits sold online you'll never use in your lifetime, unless you're a professional. All the heavy duty precision scewdriver bits are made of premium 6150 CR-V Steel with hardening treatment and bright chrome plating. The aluminum alloy handle are made by CNC technology, works for big torque, you can put more strength by putting a lever into screwdriver's hole. The built-in strong magnetic can hold the bits easily and firmly.
