DEWALT DT70747T-QZ 36-Piece Impact Torsion Screwdriver Bit Set with Tough Case+

High-torque fastening jobs demand bits that won't strip, snap, or round off under pressure. The DEWALT DT70747T-QZ 36-Piece Screwdriver Bit Set answers that call with S2 modified steel bits engineered for impact drivers and heavy-duty applications. Each bit features an Extreme Impact Torsion zone that absorbs and redistributes peak torque, while the optimised tip geometry grips screw heads firmly to reduce cam-out. From PH2 to T30, the set covers the most common drive types in both 25mm and 50mm lengths, so you're ready for everything from cabinet hinges to deck framing.

Who is it for

Professional carpenters, electricians, HVAC technicians, and serious DIYers who use impact drivers daily. If you're tired of replacing worn bits mid-project or fighting stripped screws, this set is built for you.

Tips

For maximum bit life, match the bit type and size exactly to the screw recess. Let the impact driver do the work—avoid excessive downward pressure, which can cause cam-out. Store the set in its Tough Case+ and connect multiple cases for a modular storage system that keeps your bits organised and accessible.
