Absolutely. This set includes the Pentalobe (0.8mm), Y-Type (0.8mm), and specific Phillips bits for iPhone battery and screen screws. It also includes Torx and Triangle bits for most Android devices (Samsung, Xiaomi, Google Pixel), making it a complete smartphone repair solution.
Standard CRV bits have a hardness of 50-55 HRC and are prone to deforming under heavy torque. S2 steel undergoes specialized high-temperature quenching to reach a steady HRC60± hardness. This means S2 bits resist wear, twisting, and edge damage much better, protecting both the bit and the expensive screw heads on your phone.
These bits feature a standard H4 hex shank (28mm length). They are compatible with most precision electric screwdrivers, magnetic driver handles, and handheld miniature torque tools designed for electronics repair. If your tool uses a standard 1/4" hex chuck, you will need a H4-to-1/4" adapter.
The magnetic tip is engineered for secure one-handed driving. It holds standard smartphone screws (M1.4 to M2.5) firmly even when the bit is vertical. This is perfect for precise alignment in tight spaces like battery compartments or camera lens covers without dropping screws.
