How to use

Insert the 1/4" hex shank into a compatible screwdriver chuck or bit holder until it locks. Ensure the PH1 tip matches the screw head size and is properly seated to minimize slipping. Apply steady, controlled torque appropriate to the screw and material; when using a powered driver, start at low speed to maintain alignment and avoid overtightening. Remove the bit by releasing the holder or chuck according to the tool manufacturer's instructions.

Usage recommendations

For best results, use the Proline PH1 bit with screws that match the PH1 size and avoid excessive side load that can deform the tip. Inspect the tip for wear before use and replace the bit if the profile is rounded or damaged. When working on delicate materials or electrical components, use appropriate torque settings and personal protective measures.
