How to use

Insert the Proline bit into the 1/2" drive holder or adapter until it seats securely. Ensure the bit type and size match the screw head before applying torque.

Use appropriate personal protective equipment when working with powered drivers. Store the bit in a dry, organized tool case to prevent corrosion and damage. For consistent results, match the bit to the specific screw head profile and avoid excessive torque beyond the driver or fastener rating.
