Features:
Covers common sizes from small screws to medium bolts—perfect for automotive repair, machinery maintenance, metalwork, woodworking, and DIY.
Made from premium HSS with titanium coating, these reverse drill bits provide superior hardness, heat resistance, and faster drilling. The left-hand rotation helps loosen broken bolts automatically during drilling.
The high-strength CR-MO alloy steel extractors feature a deep spiral groove design that grips broken bolts, screws, or studs securely—ideal for rusted, seized, or rounded fasteners.
The left-hand bits use a 135° angled head for easy centering, reduced walking, and smooth chip removal. Produces clean holes and more efficient extraction compared with standard drill bits.
Comes with a center punch for precise drilling alignment, plus a compact storage case that keeps every bit organized, protected, and ready for use anywhere.
Effectively removes broken bolts and screws from metal surfaces, wooden boards, automotive parts, engines, and mechanical equipment.
Most electric drills, cordless drills, and drill presses—no special tools required. Suitable for auto technicians, carpenters, machinists, mechanics, plumbers, and home repair users.
