This is the perfect screwdriver for electricians needing to travel light. Why carry 6 screwdrivers when one will do the job? The handle contains 6 Slim VDE blades: 3mm, 4mm and 5mm slotted, Phillips PH1 and PH2, and an MCD (terminal slotted/Pz2). Wiha's Slim VDE design means that these fully VDE tested blades are up 33% thinner than standard VDE screwdrivers, for safe and easy access to recessed screws. A simple press of a button causes the blades to "Lift Up" out of the top of the handle for quick selection. When not in use the handle contains the bits securely. The blades are chrome vanadium steel fully through hardened with the insulation moulded directly onto blade. The handle features Wiha’s SoftFinish multi-component construction with roll-off protection. The insulated ClicFix bit holder locks all slimBits reliability. Suitable for 6mm slimBits only, not for use with bit styles C 6.3 and E 6.3.
