A ratchet screwdriver is one of the most beneficial tools you can have in your toolkit. Having a quality single ratchet screwdriver with a good selection of bits can take the place of an entire screwdriver set; they are compact and easy to use. Having a full selection of bits that fit your ratchet screwdriver is vital. Have a range of sizes and styles including flat-head bits, Phillips head bits and square drive bits to ensure you’ll be able to handle all types of screws. Bit holder sockets typically work with screwdriver bits using magnetic, C-clip, or locking retention and are designed to be temporary bit-holding solutions.
