Alpha 10 Piece Screw Extractor & L/H Cobalt Drill Set - 9SECOL-SET10
The Alpha 9SECOL-SET10 offers a comprehensive, two-stage strategy for removing snapped studs, stripped screws, and broken bolts without damaging the surrounding thread. This professional kit pairs heavy-duty spiral extractors with premium Left-Hand Cobalt drill bits. Often, the heat and reverse torque generated by the left-hand drill are enough to spin the broken fastener out during the drilling process, saving you the hassle of using the extractor entirely. If the bolt remains stuck, the matched extractor provides the aggressive grip needed to finish the job.
Features:
Left-Hand Drill Action: The drill bits are designed to cut in reverse (counter-clockwise), applying torque in the direction of removal which often unscrews the broken bolt before you even reach for the extractor.
Cobalt HSS Construction: Drills are manufactured from High-Speed Steel with Cobalt content, providing the extreme heat resistance and hardness required to drill into high-tensile bolts that would destroy standard bits.
Spiral Tapered Extractors: Features an aggressive spiral flute design that digs deeper and grips tighter as more torque is applied, ensuring the tool doesn't slip inside the pilot hole.
135° Split Point: The drill bits feature a self-centering 135-degree point that bites immediately into uneven or jagged broken surfaces, preventing the bit from wandering and damaging the internal threads.
Matched Pairing: Each extractor is paired with the perfectly sized drill bit, eliminating the guesswork of selecting the right pilot hole size and ensuring maximum wall thickness is left on the extractor for strength.
