Looking for a solid cordless drill for my tool box at my new job as a maintenance tech. Out of 5 coworkers, one swears by porter cable, another milwaukee, and another dewalt. The other two use what ever is on sale. I will mainly be using this drill for nearly everything from drilling metal plates to basic bit driving. The company provided milwaukee drill has been abused for awhile and is built like a tank but the batteries dont last long at all. My interest is in the 20v flavor of either porter cable or dewalt since both are on sale right now for virtually a 20-40 dollar difference at my local lowes. Im not interested in a 5 or more tool combo pack for 3 or 400 bucks. Just a good solid drill that will hold up to machine maintenance and upkeep type of work. What say you bitgoers?
