Screwdriver bit Wera Kraftform Kompakt VDE 64 i, Hex 4.0 x 157 mm, insulated VDE

The Wera Kraftform Kompakt VDE 64 i, Hex 4.0 x 157 mm, insulated VDE is a compact insulated hex screwdriver bit designed for work near live electrical circuits. The tool combines VDE-certified insulation with the Kraftform ergonomic profile to provide controlled torque transfer and a comfortable grip when used with compatible bit holders or compact screwdrivers. Its 4.0 mm hex tip and 157 mm length make it suitable for reaching recessed fasteners while maintaining electrical protection.

Advantages

The VDE insulation is certified for safe use on live parts up to the specified test voltage, reducing the risk of electrical shock when used correctly. The Kraftform handle geometry and compact format enable precise torque application and reduce hand fatigue during repetitive tasks. The longer 157 mm shaft gives extended reach for recessed or hard-to-access hex sockets without sacrificing control. High manufacturing tolerances maintain tip fit and minimize cam-out, improving efficiency and reducing damage to fasteners.

Suitable for

• Electrical installation and maintenance where insulated tools are required
• Servicing household appliances with hex fasteners in confined spaces
• Industrial maintenance tasks involving live or potentially live circuits
• Electricians, technicians, and maintenance professionals needing insulated hex bits

How to use

Insert the Wera Kraftform Kompakt VDE 64 i hex bit into a compatible insulated bit holder or compact screwdriver that accepts 4.0 mm hex bits. Before use, verify the insulation is intact and free of damage. Use the tool only within the insulation's rated voltage limits and follow applicable safety procedures for working on or near live equipment. Apply steady, controlled torque and ensure the bit is fully engaged in the fastener to avoid slippage. After use, inspect the insulated coating and tip for wear or damage and replace if compromised.

Usage recommendations

Use this insulated hex bit in accordance with local and international electrical safety standards. Do not use the tool if the insulation is cracked, cut, or otherwise damaged. Store separately from uninsulated tools to prevent abrasion of the coating. For work beyond the rated voltage or specialized applications, choose tools and personal protective equipment appropriate to the risk.
