Over the past couple of years, DeWalt has focused on making the transition to Li-ion technology, and now all 40 of its 18-V tools can use Li-ion batteries. One of DeWalt's newest products is the 18-V DC827KL Impact Wrench/ Driver. It produces 1330 in/lbs of torque with a no-load speed up to 2400 rpm and up to 2700 impacts/ minute. At 3.7 lbs and 5¾ in. long, the compact driver allows access to tight areas and minimizes user fatigue.
