Everyone needs a good screwdriver, but endlessly twisting screws can make your skin raw. Using an electric screwdriver can speed things up and make your job a lot easier. Many have changeable heads so you can easily switch depending on the size and type of screw you are working with. Investing in a good cordless screwdriver means you can work anywhere. This type of screwdriver often uses a rechargeable battery pack for hours of uninterrupted use. Electric screwdrivers can work in forward or reverse, meaning that you can screw something in or unscrew it. These tools are a perfect addition to any toolkit.
