BOSCH Electric Screwdrivers
Electric screwdrivers are electric tools that can tighten screws and make holes. They are mainly separated into 2 types: drill driver and impact driver. Drill drivers have particularly fast tip part rotational speed, so they can be used as drills in addition to tightening screws by changing the bit. Impact drivers have particularly strong tightening force (torque) and apply impact while turning screws, so they are suitable for driving large volumes of long screws and for tightening wood screws. Both can be used with even greater convenience by changing the bit at the tip part according to the application. Electric screwdrivers can be AC-powered or cordless battery-powered. AC-powered types are supplied with power from an AC outlet, so there is no need to worry about batteries running down and the like, making them suitable for working for long periods of time. Battery-powered types are very portable as they do not have a cord, making them suitable for carrying around and work outdoors.
