Klein Tools' Interchangeable Insulated Screwdriver Set includes an insulated handle and 5 interchangeable insulated blades for quick changes on the job. The auto-eject mechanism works with just a twist, allowing you to change or flip blades simply and easily. A bright orange coating of insulation protects from electrical shock, as well as being flame and impact resistant. Klein insulated tools exceed the ASTM F1505 standards for insulated tools, and are clearly marked with the official 1000-volt rating symbol. The set of five Phillips, Square and Slotted slim-tip blades come in a protective roll pouch, making this the perfect set for your tool bag.
