The 18v ratchet wrench--a high performance power tool engineered to provide unequaled functionality and productivity in a wide range of settings. What it does best is help people undo all the kinks in their projects by loosening and tightening nuts and bolts; a process that demands precision at least equal to what they were given for mating screws. Technology-wise: The high-torque motor, variable speed trigger, and automatic shut-off (to prevent over-torqueing) are state-of-the-art. Its sleek, ergonomic design makes for comfortable use over extended periods. Plus, the built-in LED work light helps you see everything in even pitch-black spaces. With applications ranging from automotive and manufacturing to maintenance and repair, this multi-purpose tool is the characteristic property of professionals as well as DIY devotees.
