Insulated screwdrivers are critical safety tools for any kind of work involving electricity. They are made of non - conductive materials that cover the metal parts of the screwdriver, fully protecting users from electric shock. The insulation for the screwdriver’s tips is often made from high – quality plastics or rubbers that have been put through rigorous tests such as ASTM or VDE. These screwdrivers are marked or manufactured in colors that distinguish them as insulated, so they can be easily and quickly identified. The handles of these screwdrivers are ergonomically designed to allow users to firmly grip it while keeping the insulation intact. Insulated screwdrivers are important for technicians and electricians when dealing with live electrical circuits or in places with potential electrical threats.
