Dimensions: 52 x 50 x 29 mm (W x H x D). Application: For magnetizing and demagnetizing blades and blade-like tools made of steel. Quick and easy magnetizing and demagnetizing. Extremely durable permanent magnet. Easy to clean thanks to the smooth surface. When screwing, it often happens that the screw falls or gets lost. The Wiha magnetizer addresses this problem. It allows for quick and easy magnetization of the screwdriver tip, making it much easier to pick up screws and small parts. To demagnetize, the screwdriver is slid over the steps multiple times until it is demagnetized. The strong permanent magnet of the tool is highly durable.
