Expert quality XP1000, slimline screwdrivers with insulated sheaths the same diameter as the blades, enabling access to deep-seated screws found in terminals and switchboards. The patented dual-layer insulation ensures damage is highly visible. A set of six blades in the most commonly used sizes. Individually tested to 10,000V, suitable for working on live circuits of 1,000V AC and 1,500V DC. Ergonomic soft grip bi-material handle allows free spinning in the palm of your hand to quickly tighten screws, but also allows transfer of torque when needed. Designed with flat sides to prevent them from rolling. SVCM steel blades hardened, tempered and chemically blackened with a precision-machined tip for exact fit to prevent screw damage.
