This cordless impact driver is compact, light and portable with a hex. 1/4" drive shank. A small and light tool that is easy to use but offers a maximum fastening torque of 155 Nm, suitable for quick driving. It has a handy LED light for added lighting.
 
Note: Impact drivers and impact wrenches are both high-torque impacting tools, but they serve different purposes. Impact drivers (1/4" hex) such as this one are best for driving screws and smaller fasteners in wood/metal. Impact wrenches (square drive) are designed for heavy-duty loosening and tightening of nuts and bolts, typically in automotive or heavy construction projects.
