## Long description

DeWalt DT7999T-QZ is a 5-piece screwdriver bit set featuring PH3 Phillips tips with a 50 mm length and a hexagonal shank designed for quick-change holders and impact drivers. The set is supplied in a compact box and is intended for fastening larger Phillips-head screws in construction, woodworking and mechanical assembly applications where reach and torque transfer are important.

How to use
Select a PH3 bit from the box and insert the hex shank into a compatible quick-change chuck, bit holder or impact driver.
