Wera series 162I Phillips insulated screwdrivers are tested individually for dielectric strength under a load of 10,000 volts so as to ensure safe working with loads up to 1,000 volts. They have a premium Lasertip, a tip which has a laser roughened surface which literally bites into the screwhead, reducing cam-out and eliminating the need for two-handed screwdriving. They have a significantly extended service life due to bit-grade steel used in all Wera screwdrivers and have the patented Kraftform handle which is ergonomic, multi-component and which uniquely fits to the shape of the hand during screwdriver use, reducing fatigue and increasing speed. Smooth, soft zones offer improved grip, hard zones allow easy hand repositioning.Blade Length, 80mmTip, Phillips PH0
