Flat screwdriver STAHLWILLE 0.8 x 4.0 x 100 mm VDE 1000V DRALL+

Insulated flat screwdriver STAHLWILLE DRALL+ with a blade tip of 0.8 x 4.0 mm and a 100 mm blade length. The tool is designed and tested for electrical work up to 1000 V in accordance with VDE standards. It combines an ergonomic handle profile with a twisted DRALL+ blade geometry to improve seating on fasteners and enable controlled torque transfer while working on live circuits within rated voltage.

Advantages

The screwdriver offers electrical insulation certified for use up to 1000 V, reducing the risk of accidental contact with live parts when used properly. Ergonomic handle geometry increases grip comfort and reduces hand fatigue during repetitive tasks. The DRALL+ twisted blade profile provides better engagement with slotted screw heads, helping to prevent cam‑out and enabling more precise torque application. The 100 mm blade length provides access to recessed screws while maintaining control and stability.

Suitable for

• Electrical installation and maintenance on live low-voltage circuits (up to 1000 V)
• Assembly and repair of electrical equipment and control panels
• Work on domestic and industrial switchgear where insulated tools are required
• Precision tasks requiring a small flat tip and good screw engagement

Key specifications

• Blade tip width and thickness: 4.0 mm x 0.8 mm
• Blade length: 100 mm
• Insulation rating: tested for electrical work up to 1000 V (VDE)
• Blade profile: twisted DRALL+ for improved screw engagement
• Handle: ergonomic design for secure grip and reduced fatigue

How to use

Confirm the tool's insulation integrity before use by checking for visible damage to the handle and blade coating. Use the screwdriver only on circuits that are known to be within the rated voltage and in accordance with applicable safety procedures. Insert the flat tip into the screw slot with firm, controlled pressure to maintain full contact; apply torque through the handle while keeping the blade aligned with the screw to avoid slippage. After use, store the insulated screwdriver in a dry, clean place and periodically inspect the insulation and blade for wear or damage.

Usage recommendations

Use personal protective equipment and follow local electrical safety regulations. Do not use the insulated screwdriver on circuits exceeding the rated 1000 V, on live parts if the tool shows signs of damage, or as a pry bar or chisel. Regularly inspect the insulation coating and replace the tool if the protective layer is compromised.
