FAQ

Q1: What is the difference between S2 steel and CR-V steel? Which is better for air tools?
A: S2 steel is a high-performance alloy tool steel with significantly higher hardness and impact toughness than CR-V (Chrome Vanadium). For the high-frequency, high-torque impacts generated by pneumatic screwdrivers, S2 bits are much less likely to chip or break, offering a longer service life.
Q2: Are these double-ended bits compatible with my electric screwdriver?
A: Yes, these bits feature a standard 6.3mm (1/4 inch) hex shank, making them compatible with almost all electric screwdrivers, pneumatic screwdrivers, and quick-change adapters on the market.
Q3: What is the Minimum Order Quantity (MOQ)?
A: Our standard carton quantity is 1800 pcs. We support mixed batches; you can combine different sizes (PH or SL) from the table. Please contact our sales manager for specific MOQ details.
Q4: Do you provide samples for testing?
A: Absolutely. We welcome global clients to request samples. The sample fee will be refunded in your subsequent bulk order.
