Power screwdriver/impact driver Dedra DED7974 18V 2-speed

The Dedra DED7974 18V 2-speed power screwdriver and impact driver combines a compact build with a two-speed gearbox to deliver adaptable performance for a wide range of fastening and light drilling tasks. Designed for both professional and DIY users, this cordless tool provides high torque for driving screws and for impact-assisted fastening, while the ergonomic handle helps reduce user fatigue during extended work sessions.

Advantages

The 18V motor produces the torque needed for demanding screwdriving and moderate drilling tasks. A two-speed gearbox lets you switch between higher speed for drilling and higher torque for fastening. The compact, lightweight housing improves access in confined spaces and the ergonomic grip enhances comfort and control. Impact mode increases efficiency when working with dense or screw-prone materials.

Suitable for

• Assembling furniture and cabinetry
• Installing fixtures and fittings in domestic and commercial spaces
• Driving long screws and fasteners into wood, metal, and composite materials
• Light drilling and hole preparation where impact assistance is beneficial

Key specifications

• Supply voltage: 18 V
• Two-speed gearbox for adjustable speed and torque
• Impact driver function for increased fastening power
• Compact, ergonomic housing for improved handling
• Suitable for cordless operation with compatible batteries and chargers

How to use

Select the appropriate bit for the fastener or drilling task and install it securely in the chuck. Choose the lower speed/ higher torque setting for screwdriving and impact-assisted fastening, or the higher speed setting for drilling. Adjust torque or clutch settings if available to match the fastener and material, then apply steady, controlled pressure while driving screws or drilling. Release the trigger to stop and check progress frequently to avoid overdriving or damaging the workpiece.

Usage recommendations

Use high-quality screwdriver bits that match the fastener head to minimize slipping and wear. For extended runs of fastening work, use a fully charged battery and allow intermittent cooling breaks to maintain tool performance. When drilling into metal or masonry, use the correct bit type and start at low speed to maintain control. Store the tool in a dry place and follow manufacturer guidance for battery care and charger compatibility.
