Have you ever had to halt a project temporarily and ever so frustratingly? Just to switch from a square-recess bit to a Phillips head? Ever drop the switcheroo into the bilge? Forget about all that stuff. Now there’s the WORX SC SemiAutomatic Driver from Rockwell. With a long-lasting lithium-ion battery and a rotating circular magazine that holds six different 1-inch-long hex-shanked bits (much like a revolver holds cartridges), the WORX SC automatically changes from bit to bit each time the magazine cover is snapped back. Holster not included, though we wonder why.
