Can I choose S2 or CR-V bits for an OEM screwdriver set?

Yes. You can choose either S2 or CR-V bits for an OEM screwdriver set, depending on the target quality level, application, and price.

A practical comparison is:

S2 steel: better for professional and precision repair sets

CR-V steel: better for general-purpose and price-sensitive sets

S2 hardness: typically around HRC 58–62

CR-V hardness: typically around HRC 52–56

S2: better wear resistance and tip retention

CR-V: good toughness and lower material cost

For phone, laptop, camera, watch, and electronics repair, we normally recommend S2 bits because accurate small tips need better wear resistance.

For household, DIY, or entry-level screwdriver sets, CR-V can provide a better cost-performance balance.

It is also possible to use S2 for critical precision bits and CR-V for less demanding sizes within the same OEM set to control cost without reducing the quality of the most important bits.

For ToolQeen OEM projects, buyers can customize the bit material, hardness, profiles, lengths, quantities, surface treatment, and set configuration according to the target market and price level.
