A miracle tool for anyone who regularly needs to install long screws, fasteners and bolts, the impact driver should be part of the arsenal of any tradesperson and serious DIYer. Available to be purchased as a stand-alone impact driver or as a duo with a powered screwdriver, for large projects this power tool saves a lot of time and effort.
Similar in its operation to a powered screwdriver, a rotational force is used to drive the fastener or screw into the material. However, when the impact driver encounters resistance, it automatically provides a burst of quick power. This extra torque provides the extra power needed to more efficiently drive longer screws or fasteners into tough materials.
