Hitachi DS 18DBL Cordless Driver Drill

This 18-volt model is the only one here that isn't an impact driver, so it can't bite into concrete. A bummer, but its 593 in./lbs of torque sent a four-inch screw through Douglas fir in no time. Grundy had no performance complaints, but found that getting a battery reading wasn't intuitive when checking remaining levels on the spot. [$300;]
