The DEWALT DT70730T FLEXTORQ™ Screwdriving Set contains a selection of EXTREME FlexTorq™ screwdriving bits engineered for longer life. The built-in torsion zone has been designed to absorb and control high-impact forces, transferring them into the optimised geometry of the bit tip. Reducing the load on the driver and fastener, means secure fixing with longer life. The full fit head eliminates wobble and screw head rounding.
