DeWalt's FlexTorq screwdriver bits are impact rated for use in impact drivers and feature extended FlexTorq torsion zones which are designed to asborb extreme forces, transferring them to the optimised geometry of the bit tip. Reducing the load on the driver and fastener means secure fixing with longer service life. These accessory sets are supplied in ToughCase storage organisers with transparent lids for quick identification. Multiple ToughCases can be slotted into a TSTAK caddy for ease of transport, whether using the built in handles or integrated into a wheeled trolley stack. The robust, easy to use interlocking system means that units can be configured to individual requirements, providing the ultimate flexible storage and transport solution for tools, fixings and accessories. Features and Benefits • Full fit heads eliminate wobble and screw head rounding • Contoured area of the bit tip flexes with the torque of the driver • Optimised torsion zone, maximising bit life and turning
