Klein recently released the Switch Drive System, a handle that works with any 1/4-inch hex bit with a groove to hold it in. What’s cool about the system—and why it’s better than a traditional multi-driver—is the selection of available bits. The Power Driver Set (32700) includes a handle and a #2 Phillips and #2 square drive bit. The short bits and fat shafts of traditional multi-drivers tend to impede access. That won’t be a problem with the Switch Drive tool because the screwdriver bits are long and thin—like those of a regular screwdriver.
A quick-release mechanism on the handle makes it easy to swap or remove bits. When a task requires finesse the bit can be used in the handle; when it requires strength it can be used in a drill or impact driver. It’s a convenient setup because it allows the tradesman to perform multiple operations with a minimal quantity of gear: a handle, power tool, and a bunch of easily stored bits.
In addition to the Power Driver Set, the tool is available in Power Nut Driver Set (32701) that includes a handle plus 1/4”, 5/16”, and 3/8” magnetic nut drivers.
You are not limited to the bits and drivers that come with the handles. The handles will accept any 1/4-inch hex bits and Klein makes a bunch of them: screwdriver bits, nut drivers, multi-bit driver bits, and a conduit reamer. All are impact rated and most come in multiple sizes and lengths.
