Extract stubborn sheared fasteners, stripped screws, and seized threaded studs without damaging surrounding threads. The 10-Piece Cobalt Left-Hand Drill Bit & Damaged Screw Extractor Set with Metal Storage Case is forged from premium M35 cobalt high-speed steel paired with heat-treated alloy steel multi-flute extractors. Designed to operate in reverse drilling rotation, the reverse-twist drill bits often catch and back out broken bolts during pilot hole drilling alone, while the aggressive spiral-fluted extractors grip deeply to break free the most stubborn corroded or cross-threaded fasteners.
Key Features
Reverse-Direction Left-Hand Bits: Cutting flutes engage in counterclockwise rotation, using pilot drilling friction and torque to frequently spin out broken hardware without needing an extractor.
M35 Cobalt High-Speed Steel: Engineered with cobalt alloy content to resist intense operational heat, retaining razor-sharp cutting edges even through hardened bolts, studs, and stainless steel.
Aggressive Multi-Flute Screw Extractors: Precision-machined, reverse-tapered alloy steel extractors bite into pre-drilled pilot holes to deliver non-slip turning leverage against seized hardware.
135-Degree Split-Point Tips: Self-centering drill tips prevent bit walking or wandering across uneven sheared bolt heads, eliminating the need for a center punch.
Heavy-Duty Protective Metal Index Case: Rugged steel carry box keeps bits and extractors labeled, secured, and shielded from workshop drops and impact damage.
Comprehensive Fastener Coverage: Matched bit and extractor pairings handle extractions ranging from small recessed machine screws up to heavy-duty automotive chassis bolts.
