Tool Review: Kobalt 62731 32-Piece Double Drive Screwdriver Set

Key Features:
 +   Double Drive feature allows for turning screws almost twice as fast
 +   Good bit selection included
 -    Awkward to use at first


Kobalt's Double Drive screwdriver is a ratcheting screwdriver, similar to many other ratcheting screwdrivers.  But the main difference lies in the fact that when you use the ratcheting function, the driver bit turns whether you are turning the handle forward or backward.  On a normal ratcheting screwdriver, the bit turns when you turn the driver one way, but when you ratchet it back the bit stands still.  On a Double Drive screwdriver, the bit turns when you turn the driver one way, but when you ratchet it back, the bit also turns, in the same direction.  So you can effectively turn a screw twice as fast with the Double Drive screwdriver as you could with a normal ratcheting screwdriver.

The Double Drive function only works when you use the screwdriver in a certain way -- gripping the metal part of the handle -- so you are still able to use it as a normal ratcheting screwdriver, if you prefer; or, you can even use it as a non-ratcheting screwdriver if you hold the handle in the right spot.  The driver has an easy-to-reach vertical thumb switch, which makes switching directions much easier than on other ratcheting drivers that have horizontal switches.

The two screwdrivers included in this set are almost identical except for their size.  Both have the Double Drive capability and the same thumb switch, but the larger driver has a removable cap that allows for bit storage in the driver itself.  There is a lot of room, so many bits can be stored in there.  The set comes with bits for both the large and small drivers.  The bits for the larger driver are standard 1/4" hex bits, and the bits for the smaller driver are precision bits.

Once you get the hang of how to use the Double Drive function, the drivers are not difficult to use.  However, there is a learning curve with them.  They are much heavier than standard screwdrivers, but not significantly heavier than other ratcheting screwdrivers.  The handles provide adequate grip.  The drivers are not magnetic.

There are a few different Double Drive sets that Kobalt sells.  This 32-piece set includes a large driver, a smaller precision driver, and a plastic case with many different sizes and types of bits in it, including some Torx bits.  Other Double Drive sets include pouches or holsters and extension bars, but might not include the precision driver.  Lowes.com sells this Double Drive set for just $9.98 -- a great deal for two ratcheting screwdrivers with bits.
