Wera 897/4 IMP R Impaktor Magnetic Screwdriver Bit Holder

The Wera 897/4 IMP R Impaktor Magnetic Screwdriver Bit Holder is a specialist bit holder designed to absorb extreme impulse peaks when used with impact drivers and power screwdrivers. At the heart of this holder is a double-torsion spring mechanism that creates a special torsion effect, protecting both the bit and the tool from the intense rotational forces generated by impact drivers. This makes it particularly well-suited to demanding fastening applications where a standard bit holder would be at risk of premature wear or failure. The integrated ring magnet securely holds longer and heavier screws in position, allowing for rapid and accurate screw placement — a genuine advantage when working overhead or in awkward positions where a dropped fixing costs time. Should the magnet be undesirable in the working environment, such as when driving screws into sheet metal or other ferrous materials, it can be moved away from the screwdriving zone and effectively neutralised without removing it entirely. Compatible with ¼" hexagon shank bits to DIN ISO 1173-C 6.3, this holder fits power screwdrivers with a ¼" hexagon drive as per DIN ISO 1173-F 6.3, making it a straightforward addition to most existing impact driver setups.
