7 piece VDE Screwdriver Set. Each individual screwdriver is tested to ensure it fulfils the EN 60900 requirements. The EN 60900 requirements compel all tools to be tested to 10kV, making them suitable for working on live AC circuits of up to 1kV and DC circuits of up to 1.5kV. The blades on the screwdrivers are manufactured from SVCM+ alloy steel, hardened, tempered and chemically blackened, with a deep-set blade sheath providing total safety and peace of mind. All blades are fitted to a fully insulated, ergonomic soft grip handle delivering user comfort even when used for prolonged periods. A great VDE screwdriver for professional electricians.
