Wiha SB 400 10 magnetizzatore / smagnetizzatore 52 mm x 50 mm

Magnetized screwdriver tips can attract small screws, making them easier to hold in place, but they can also attract metal shavings that interfere with precision work. The Wiha SB 400 10 magnetizer and demagnetizer solves both problems in one compact tool. Simply slide a screwdriver tip, tweezer, or small metal part through the appropriate slot to magnetize or demagnetize it. No batteries or power source needed—it works by magnetic induction.
