The Sealey Premier 8 Piece VDE Interchangeable Screwdriver Set is a selection of insulated screwdriving blades and accessories for anyone working with electricity. The screwdriver blades can be used on their own to let you work in locations where space is incredibly limited, or for additional grip and torque transfer, can be added into the impact resistant handle with a contoured, comfortable grip and switch release mechanism. Each one of the screwdriver blades locks securely into the handle to prevent it from slipping out. The blades are made from hardened and tempered chrome vanadium steel shafts with magnetised tips along with a phosphate finish for resistance to corrosion. Supplied in a handy storage case, each part has been insulated and VDE approved for use up to 1000V AC and 1500V DC.
