Like its 21-piece cousin, the focus of the DeWALT DW2163 37-Piece Screwdriving Set in Tough Case is durability. These heat-treated bits are made to withstand a beating, and their superior hardness provides higher torque and driving power. Moreover, the tips are designed to minimize the ever-frustrating hassle of stripping. The noteworthy difference between the two is that you get a Compact Magnetic Drive Guide with the 37-piece set, which will help you minimize wobbling and slipping. For users who need durability, the DW2163 is a good pick.
