The Klein Insulated SL/PZ1 Screwdriver from ITS is a VDE, 1000V Rated driver which incorporates an ergonomic grip that provides better handling as well resulting in greater torque transfer. The Anti-Roll design prevents loss if you need to place it down, but also allows for a stronger grip, while the slimmer tip allows you to gain easier access to smaller spaces including circuit breakers. The durable and molded insulation meets or exceeds the IEC 60900 and ASTM F1505 standards for insulated tools.
