The Sirius 12 Piece Screw Extractor and Drill Set provides a complete solution for removing damaged, sheared, or seized screws and studs ranging from M3 to M25. Designed for fasteners of medium tensile strength, it pairs six numbered extractors with six precisely matched HSS drill bits, giving tradespeople everything needed for the job in a single kit. Ideal for engineers, mechanics, and maintenance contractors dealing with corroded or broken fixings, the set covers an extensive size range from small M3 fasteners right up to M25 studs. Each extractor is matched to its corresponding drill bit size, removing the guesswork and ensuring the correct pilot hole is drilled before extraction. The drill bits are fully ground HSS jobber length, manufactured to DIN 338 and BS 328 standards, confirming their quality and dimensional accuracy. Important: screw extractors should always be used with an appropriate tap wrench — using them with a power drill significantly increases the risk of snapping the extractor. All 13 pieces, including the storage case, are housed in a robust plastic case to keep the set organised and protected on site or in the workshop.
