The Irwin Hanson 537 Series Spiral Screw Extractor and Drill Bit Combo is engineered to remove broken studs, bolts, socket screws, and fittings quickly and reliably. The aggressive left-hand spiral design embeds deeper into the damaged fastener as resistance increases, delivering a stronger grip the harder you turn — no slipping or camming out.
Each extractor and matching high-speed steel drill bit are clearly etched with their size and recommended drill bit pairing, taking the guesswork out of the job. The HSS drill bit provides fast, clean hole entry, and the matched extractor size ensures a secure bite every time.
