How to use

Select the appropriate bit profile and size for the screw head to avoid cam-out and damage. Insert the bit securely into the impact driver or drill chuck and ensure correct seating before applying power. When using an impact driver, operate at controlled power settings and apply consistent axial pressure to maintain engagement between bit and screw. Inspect bits periodically for wear or deformation and replace damaged bits to maintain safe and effective operation.

Usage recommendations

For optimal lifespan, use the impact-rated bits only with tools designed for impact operation and avoid using them as pry bars or chisels. Store bits in their case to prevent loss and corrosion, and match bit size precisely to the screw head to minimize wear and slipping.
