Wera Kraftform VDE 7-Piece Insulated Screwdriver Set

In-Depth Look

The Wera Kraftform VDE set gives an electrician a set of insulated slotted and Phillips screwdrivers in one rack, along with a voltage tester screwdriver.

VDE Rating

The drivers are marked 1000V and IEC/EN 60900 on the shaft. IEC 60900 is the standard for insulated hand tools for work up to 1,000V AC. Insulated tools are one part of safe working near live or potentially live parts, alongside safe isolation and a suitable risk assessment. Check the insulation for cuts or damage before each use and replace any damaged driver.

Voltage Tester Screwdriver

The set includes a single-pole voltage tester screwdriver. It is not a substitute for a two-pole voltage indicator when proving a circuit dead; HSE guidance GS 38 recommends a two-pole voltage indicator for that job.

Kraftform Handle Design

The Kraftform handle is a multi-component design, with harder material where torque is applied and softer material where the hand grips. It is designed to help grip and comfort during long spells of terminal work.

Tips

Wera describes these as laser tip drivers. A good fit between the driver and the screw head helps reduce cam-out, where the driver slips out under torque and damages the screw.

Set Contents

The 7-piece set has slotted drivers in 2.5, 3.5, 4.0 and 5.5mm, Phillips PH1 and PH2, and a single-pole voltage tester screwdriver. There are no Pozidriv drivers in this set.

Summary

The Wera Kraftform VDE set is a 7-piece insulated screwdriver set rated for work up to 1,000V AC and marked to IEC/EN 60900, with Kraftform handles and a single-pole voltage tester.

How It Compares

The Wera Kraftform VDE set has seven pieces in a rack. There are four slotted drivers with blade widths of 2.5, 3.5, 4.0 and 5.5mm, two Phillips drivers in PH1 and PH2, and a single-pole voltage tester screwdriver. The drivers are insulated for work up to 1000V AC and are marked to IEC/EN 60900, the standard for insulated hand tools. The handle has the Kraftform shape, and the tips are laser-hardened.

A screwdriver-type tester is not a replacement for a two-pole voltage indicator. For the insulated pliers marked in the same way, see the Knipex VDE pliers set, where the VDE marking is explained. For checking a socket with a plug-in tester, see the Martindale EZ150 socket tester. Our guide to tools for electricians has more.

Common Questions

Does a VDE screwdriver mean it is safe to work live? No. The insulation is one layer of protection. Isolate the supply and prove it dead first. Follow the manufacturer’s instructions and your own risk assessment, and use a competent person where required.

How do I check the insulation is intact? Look for cuts, cracks and any metal showing beyond the tip. Retire a damaged driver rather than taping it.

Which sizes do I need for consumer units and sockets? The set has slotted drivers from 2.5 to 5.5mm and Phillips PH1 and PH2. Check the screw head type on the terminals and match the driver to it, because a wrong fit can slip and damage the screw.

Can I use them as levers or chisels? No. They are screwdrivers. Using them to pry or chisel can damage the insulation and the tip.

What is the voltage tester screwdriver for? It is a single-pole voltage tester screwdriver. A screwdriver-type tester is not a replacement for a two-pole voltage indicator, so do not rely on it to prove a circuit is dead. Use the correct test equipment and follow HSE guidance.

What does the laser-hardened tip mean? The tips are laser-hardened, which is the maker’s description of how the tip is treated. It does not change the need to match the driver to the screw head. Check the fit before you turn.

Follow the manufacturer’s instructions and use a competent person where required.
