How to choose VDE screwdrivers
A screwdriver is the tool an electrician picks up most. Here's what to look for so you buy a set once, not three times.
What "VDE" means
VDE screwdrivers are insulated and individually tested for live working up to 1000V AC. Look for the VDE mark and the 1000V double-triangle symbol on the handle or blade. A screwdriver with a plastic sleeve but no markings is not the same thing.
Insulated tools are a last line of defence. They don't make it safe to work live. Follow safe isolation and your employer's procedures every time.
The tips you'll actually use
- Slotted in two or three widths, for terminals and older fittings.
- Pozi (PZ1 and PZ2) for most screws in accessories and enclosures.
- Combined slotted/Pozi, often sold as "PlusMinus" or similar, for the screws on modern breakers and RCBOs. If your set doesn't include one, add it.
- Phillips turns up less, but a PH2 is worth having.
What separates a good set from a cheap one
- Tip hardness. Soft tips round off, then chew up terminal screws. This is the main reason to spend more.
- Slim blades. Reduced-diameter insulation reaches recessed terminals that a chunky blade can't.
- Handle shape. You'll be turning these all day. Try a few in a shop if you can.
Two sets, two budgets
If money is tight, a budget VDE set from a known brand will get you working. If you can stretch, a better set is the upgrade most electricians say they'd make first.
Looking after them
Check the insulation before each use. If it's cut, cracked or worn through to a different colour underneath, the screwdriver is finished as an insulated tool. Don't use them as chisels or levers, and keep them out of the bottom of the bag where they get crushed.
