DEWALTs 12V MAX Lithium Ion Screwdriver Kit, No. DCF610S2, is compact and lightweight at only 2.2 lbs., and built for less user fatigue and comfort in hard-to-access spaces. The contoured handle design offers increased comfort, and three LEDs around the hex of the screwdriver provide improved visibility. The 1/4" hex chuck allows users to simply push the bit in to lock it in place with one hand and accepts a 1" bit tip to fit into the tightest spaces.
