Multi-Bit Screwdrivers

Everyone needs a household screwdriver for general everyday use. A superior quality multi-bit screwdriver is ideal for this situation and it is possible that you might never have to buy another, unless you wanted one for every room in the house of course (the kitchen, the workbench in the basement, the garage, etc.).

Make sure that the screwdriver you intend to purchase has flat, cross-slotted (Philips) and square (Robertson) blades in at least two sizes for each type. Certain models also include an awl, which can be used to punch holes in leather or trace marks on wood surfaces.

Bit Holding System

Some screwdrivers are equipped with a locking ring that is tightened to hold the bit in place. The locking ring used in this system is not sealed and may be damaged or jammed by particles of sand or dust getting caught in the mechanism. As a result, although there are several superior quality screwdrivers of this type on the market, certain precautions are required when using them outdoors. Make sure that the blades are easy to replace should they become damaged or lost.
Another system is comprised of a hex-shaped cavity where the bit is inserted. This system is easy-to-use and practical but the bits tend to have limited insertion depth and there is a risk that they might fall out (should the bit get jammed in the screw head for example) and get lost as a result.

But don’t let a little thing like a lost bit stop you; this system is extremely popular, replacement bits are readily available, inexpensive and offered in several lengths and a wide variety of bit-types (such as the Torx, or six-headed star configuration, for example, often used on cars and home appliances). Plus, the bits included with this system can be used with an electric screwdriver or screwdriver-drill as well.

Although hex-bits are relatively inexpensive, you should be wary of sets that include several bits for only $1 or $2: these bits tend to be of questionable quality and their edges are easily dulled, especially the Robertson heads. Ideally, Robertson bits should be made of carbide to avoid premature dulling.

Bit Storage

Many multi-purpose screwdrivers have a hollow handle where the bits are stored. Make sure to check the unit for ruggedness as well as how the storage compartment cover works. On some models, the cap on the end of the handle is removable; this may prevent you from forcing down on the screwdriver with the palm of your hand while turning.
Other models have storage slots mounted around the base of the handle, making it easier to choose and handle the bits. In this case as well, it is important to check for quality and ruggedness; the slots may widen with use, allowing the bits to fall out. In addition, make sure that the storage system does not interfere with the handling of the screwdriver.
Finally, screwdriver sets that contain a wide range and quantity of blades typically come with a storage case that allows you to easily locate, retrieve and store them.

To summarize: Make sure that the bit-change system is practical, easy-to-use and well-made in order to avoid loss of performance. The same qualities should apply to the bit storage system.

Ratchet Systems

Available on some models, ratchet systems allow you to turn the handle of the device in the direction counter to the fastening rotation (or “couple”) without removing the bit from the screw. As with lock-ring models, one must avoid contact with dust and sand in order to maintain proper functionality in these units.
