Made of S2 alloy steel, which is a high-hardness material commonly used in hardware.
Adopting a magnetic design (if the magnetism reduces after long-term use, just use a magnetizer to magnetize it), each edge can accurately lock the screws without damaging the screws and screwdriver heads.
These bits are suitable for electric screwdrivers, hand screwdrivers, electric drills, pneumatic drills, and more, making them a great replacement for lost, bent, or damaged screwdriver bits.
