How to use

Select the correct bit for the screw head and insert it securely into the bit holder or driver until it locks. Apply steady pressure and maintain axial alignment between the driver and screw to avoid slipping or cam-out. For power-tool use, start at low speed to ensure correct seating, then increase speed while controlling torque. After use, clean debris from the bits and store them in the original case or a designated compartment to prevent damage and loss.

Usage recommendations

Use the appropriate bit size and type for each screw to minimize wear and prevent damage to screw heads. When using with power tools, match the torque setting to the task and avoid excessive force. Periodically inspect bits for rounding or cracking and replace worn bits to maintain safe and efficient operation.
