October 20, 2014 – Klein Tools has introduced the switch drive handle system to alternate any accessory with a power groove between a power drill and hand tool, minimizing the number of tools and saving space, says the company.

The quick release mechanism in the handle secures any accessory with a 1⁄4-in. hex so users can move quickly from a power drill to a hand tool while maintaining strength and performance, it adds. Available in two models, the power driver set (in image) features the switch drive handle plus #2 Phillips and #2 Square 6-in. power blades. The power nut driver set includes the handle and three magnetic power nut drivers (1/4 in., 5/16 in., and 3/8 in.).
