How does bit material affect screwdriver set pricing?

Bit material affects screwdriver set pricing because different steels have different material cost, heat-treatment requirements, hardness, wear resistance, machining difficulty, and expected service life.

The main differences are:

CR-V steel: lower cost and suitable for general-purpose, DIY, and price-sensitive screwdriver sets

S2 steel: higher cost, but provides better hardness, wear resistance, and tip durability for precision and professional use

Higher-grade specialty steels: can cost more when higher torque resistance, toughness, or special performance is required

For ToolQeen screwdriver bits, typical hardness targets are:

CR-V: HRC 52–56

S2: HRC 58–62

Bit pricing is also affected by:

Bit length: long precision bits cost more than standard short bits

Tip profile: Pentalobe, Tri-point, Security Torx, and other specialty profiles can require more precise machining

Heat treatment: tighter hardness control increases processing cost

Surface treatment: black oxide, plating, or other finishes add cost

Machining accuracy: tighter tip tolerances require better equipment and inspection

Bit quantity: more bits increase both material and assembly cost

For professional electronics repair sets, S2 is usually worth the higher cost because tip accuracy and wear resistance directly affect the user experience. For entry-level or general household sets, CR-V can provide a better cost-performance balance.

For ToolQeen OEM projects, we can also use different materials strategically within one set, keeping S2 for critical precision bits while using CR-V where lower material cost is acceptable, depending on the target price and application.
