This magnetic ring magnetizes and demagnetizes 6.35mm hex shank screwdriver bits. The compact design works with most power drills and manual screwdrivers. Made from durable aluminum alloy with strong built-in magnets. The anti-corrosion finish ensures long-lasting performance in workshop environments. Simply insert the bit into the magnetic ring to magnetize the tip. Screws stay attached to the bit, reducing drops and slips during fastening tasks. To demagnetize, slide the bit in the opposite direction. This feature helps prevent metal filings from sticking to the bit when not needed. Ideal for furniture assembly, vehicle repair, hinge installation, and general DIY projects. A practical addition to any toolbox., Manufacturer: Bigbibi
