The Sealey AK8189 is a 5-piece left-hand spiral drill bit set specifically designed for extracting broken studs, screws and fixings. These specialised drill bits rotate in reverse, making them ideal for removing damaged or seized fasteners without the need for separate extraction tools. Manufactured from durable 4121 HSS steel, this extraction set provides professional-grade performance when dealing with snapped fixings in automotive, engineering and maintenance applications. The left-hand spiral design works by gripping and unscrewing the broken fastener as you drill, often removing it in a single operation. The set includes five commonly used sizes—3.2mm, 4.8mm, 6.4mm, 8mm and 8.7mm—covering the most frequent stud and bolt diameters encountered in workshop and field repair scenarios. All bits are supplied in a practical display case for organised storage and easy size identification.
