The DEWALT DT70731T 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. Supplied in a TOUGH CASE+, this is part of a connectable case system that is TSTAK™ compatible. Individual TOUGH CASES can be clipped together for easy transportation. The DT70731T screwdriver set is part of the Dewalt modular Toughcase accessory range. With the addition of the Tstak Caddy (available separately) you are able to securely store small bulk storage.
