The DEWALT DT70556T is a professional-grade 32-piece screwdriver bit set designed for extreme impact applications. Featuring Extreme Impact Torsion technology, these bits are engineered to absorb torque peaks, reducing breakage and extending bit life up to 10 times longer than standard bits. Made from S2 modified steel with an optimised tip geometry, they provide full fitment and reduced cam-out, ensuring efficient and reliable fastening. The set includes a magnetic bit holder and is housed in a ToughCase+ modular, stackable case with a clear lid for easy organisation and transport.

Advantages

Up to 10x longer life compared to standard bits due to torsion zone and premium S2 steel. Optimised tip geometry reduces cam-out and ensures full fitment. Magnetic bit holder for secure bit retention. ToughCase+ provides durable, stackable storage with clear visibility.
