The Wera 392 Kraftform Flexible Shaft Bit Holder Screwdriver is a precision bit-holding screwdriver designed for screwdriving in awkward or restricted access situations where a standard rigid shaft cannot reach. The flexible, circular shaft allows bits to be positioned at angles that would otherwise be impossible, making this tool particularly useful for contractors, joiners, and electricians working in confined spaces or around obstructions. The 1/4" hexagonal drive accepts a wide range of standard screwdriving bits, conforming to DIN ISO 1173-C 6.3. The Kraftform Plus handle is engineered with hard zones for high-speed driving and soft zones for improved grip during high-torque applications. This multi-component design reduces fatigue during prolonged use, while the quick-release chuck allows rapid bit changes without interrupting workflow. The hexagonal profile of the handle prevents the tool from rolling off surfaces when set down — a practical detail on busy job sites.
