The sealey vs0291 is an air hammer impact driver attachment designed to remove stubborn screws without damaging the heads. This specialist tool works in conjunction with a standard air hammer at low pressure, using vibration to break free corroded, countersunk, overtightened and painted screws that would otherwise be difficult or impossible to remove. The impact driver accepts a 5 16 8mm hex bit and features a .401 Parker taper shank for compatibility with standard air hammers. The vibration from the air hammer does the hard work of loosening the screw, whilst rotation is applied manually with the handle, giving you precise control over the extraction process. This makes the vs0291 particularly valuable for automotive restoration, machinery maintenance and general workshop applications where seized or damaged fixings are encountered. By combining pneumatic impact with manual rotation, it significantly reduces the risk of stripping screw heads during removal, helping you complete jobs more efficiently without damaging components. Features and benefits: combines vibration and rotation for effective screw removal prevents damage to screw heads during extraction lightweight 0.20Kg design for comfortable handling compatible with standard air hammers via parker taper shank ideal for corroded and overtightened fasteners specifications: brand: sealey nett weight: 0.20Kg shank size: .401 Parker taper bit size: 5 16 8mm , bits not included
