The DEWALT DT70535T Impact Torsion screwdriver bits feature a 15-degree torsion zone that allows the bit to flex rather than break, reducing the risk of damage. The Full Fit head design prevents the rounding of screw heads and 'cam out', ensuring better engagement and reduced slippage. The Magnetic Screwlock sleeve makes tasks quicker and easier by reducing dropped or lost screws. These bits are specifically designed for impact applications.
