How to use

Insert the 1/4" hex shank of the bit into a compatible bit holder or driver until it locks. Place the 5.5 mm slotted tip into the screw head, apply steady axial pressure, and turn the driver to fasten or loosen the screw. Use the 89 mm length to reach screws in recessed or tight locations. Inspect the tip before use and replace the bit if the tip is worn or damaged to avoid cam‑out or screw damage.

Recommendations

For best results, select the correct 5.5 mm slotted bit size to match the screw slot, use a bit holder compliant with DIN ISO 1173-F 6.3, and avoid excessive torque that can deform the tip. Store bits dry and inspect regularly for wear.
