Recommended Power Tools for Drill Screw

●Before starting installation, inspect the power tools, bits, and fasteners used.
●Follow the manufacturer’s instruction manual when using power tools.
●Use a power tool (drill driver) with a clutch function.
●Be especially careful when using the impact driver because the torque is high.
