The DEWALT® screwdriving bits FLEXTORQ® are CNC machined, resulting in accurate manufacturing for optimal fit into the screw recess. A reflex Core allows 2" bits to Flex up to 15-degrees to reduce breakage. These bits are a part of the 10x Magnetic Screw Lock System for fastener retention which minimizes drops and reduces wobbling. Impact ready bits with FLEXTORQ® have increased durability for longer life.
