The DEWALT DT70587 FLEXTORQ™ Bit Set contains a selection of EXTREME® FlexTorq™ screwdriving bits which are expertly 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 also means secure fixing with longer life, while the full-fit head eliminates wobble and screw head rounding.
