The DeWALT DT7388T-QZ screwdriver bit is a 25 mm replacement bit supplied in a pack of 5 pieces. Designed for durability and precision, the bit is intended to provide a secure fit in compatible screwdrivers and impact drivers while reducing wobble and protecting screw heads. Typical use covers both professional trades and home DIY tasks where repeatable, accurate fastening is required.

How to use

Insert the bit securely into the chuck or bit holder of a compatible screwdriver or impact driver. Ensure the bit seats fully before applying torque. Select appropriate speed and torque settings for the screw and material being worked on to avoid over-driving or stripping. Replace bits when wear or deformation is evident to maintain fastening accuracy.

Usage recommendations

For prolonged bit life, avoid using excessive torque settings on soft screw heads and store bits in a dry, protected case to prevent corrosion and mechanical damage.
