Using a cordless drill-driver correctly

In short: The cordless drill-driver is one of the most important tools for DIY enthusiasts, allowing both driving screws and drilling with the same device. Setting the right torque and speed prevents damage to materials and screws.

In more detail: Too much torque can damage screw heads or crack materials, while too little torque fails to tighten the screw securely.

In detail

• Torque setting: The adjustment ring on the drill-driver allows stepwise adjustment of force, with a lower setting suitable for delicate materials.
• Drilling function: For pure drilling, a separate, higher setting without torque limiting is usually used, since continuous power is needed here.
• Choosing bits: The right screwdriver bit, matching the screw shape exactly, prevents stripping and damaged screw heads.
• Pre-drilling in wood: Especially with hard wood or near edges, a pilot hole prevents the material from splitting.
• Battery care: Lithium-ion batteries shouldn’t be fully discharged and are ideally stored at room temperature to extend their lifespan.
• Speed control: The trigger allows variable speed control, enabling both precise and fast work.
• Safety aspects: Safety glasses, a secure stance, and securing the workpiece reduce the risk of injury when working with a cordless drill-driver (schrauben-arten-und-groessen, bohren-in-wand-duebel-richtig-waehlen).
