The wera 30 piece impaktor screwdriver bit set is a professional-grade bit set engineered specifically for use with impact drivers, delivering exceptional durability under the high-torque, high-impact conditions that quickly destroy standard bits. At the heart of this set is wera's impaktor technology, which combines optimised geometry with the best possible use of material properties to provide an above-average service life even under the most demanding site conditions. Each bit features a rough diamond coating that bites into the screw head, dramatically reducing cam-out and maintaining a secure fit throughout the drive. The set includes an impaktor holder with a retaining ring and ring magnet, making it straightforward to handle longer and heavier screws particularly useful when working overhead. With 29 impaktor bits covering phillips, pozidriv, torx and slotted formats, this set provides the versatility contractors, carpenters and general tradespeople need across a wide range of fixing applications. The bit-check case is upright positionable and multi-component, keeping bits organised and accessible on site or in the workshop.
