The VDE safety insulation of screwdrivers often prevents optimal access to low-lying fastening elements. “Wiha slimTECHNOLOGY” presents a completely VDE and GS tested solution. Ingeniously simple: insulation that often poses a hindrance has been integrated into the blades, thus creating maximum access to the fastening elements. So the slim blades achieve a reduction of diameter of up to 33% in the critical working area according to output size. The slim blades from Wiha are extremely narrow but still characterized by exceedingly high performance blades that surpass stipulations for VDE torque several times and simply get the job done.
