Working on electrical systems and wiring comes with its own set of safety concerns. The insulated tool set comes with a wide assortment of common-use tools. Set includes a 3/8 inch drive ratchet, 6 inch and 10 inch extensions, hex bit sockets, standard sockets, assorted pliers, slotted screwdriver set, Phillips screwdriver set, Torx screwdriver set, utility knife, voltage tester, and 10 pieces of cable covers. All tools are tested at 10,000 VAC and certified for 1,000VAC for peace of mind. These tools arent just safe; they are durable too, made from premium Chrome Vanadium steel for long tool life. They also feature ergonomic handles for all-day comfort. Each tool has its place in the three laser-cut EVA foam trays, perfect for keeping the tools clean and organized. The three trays pack neatly into the protective heavy-duty glass nylon injected waterproof storage case.
