Installation Notes

Insert bits should be seated fully into the bit holder before driving fasteners to avoid cam-out or tip damage. Inspect bit tips regularly and replace when rounding or wear is visible. Electricians and HVAC technicians should de-energize equipment before driving fasteners into live enclosures or control panels. Store loose bits in a designated holder to prevent loss and maintain tip geometry.
