Handle and blade fully insulated up to 1000 V to DIN EN 60900 / VDE 0682-201. Each of these screwdrivers is individually tested in a water bath for insulation breakdown under high voltage. Blades with taper tips, manufactured to the standard dimensions of slots on the screws. Fully insulated, the breakdown strength of the insulation is many times the minimum test voltage set by VDE. Each of these screwdrivers is individually tested in a water bath for insulation breakdown under high voltage. Kraftform handle made of impact resistant plastic with integral soft zones facilitates torque transmission and thus protects hand and arm. Blade of high-alloy special steel. Nicromatt chrome-plated surface, black tips or chemically nickel-coated Lasertip tips. From size 5. 5 the outside ⌀ of the insulation is the same as the tip width (helpful when working in narrow spaces).
For use at voltage up to 1000 V. Optimum working life for electrician’s screwdrivers is assured if screwdrivers always exactly match the standard screw slot size. (see tables part). Incorrect screwdriver size selection will cause damage to the screw head.
