Insulated ratcheting screwdriver combined with interchangeable slim blades. The blade release system built in the comfortable handle makes it easy and safe to change the blades without the blades falling out. The blades are 30% slimmer than the blade of a regular insulated screwdriver for better accessibility and more applications (e.g. sunken screws and spring elements). They have a 48 tooth non-conductive ratcheting mechanism. A must have tool for electricians, certified according to IEC 6090. Comes with a nylon pouch.
