The DeWalt TSTAK 100 Piece Drill and Screwdriver Bit Set is a comprehensive power tool accessory kit designed for professional tradespeople who need a versatile, well-organised solution for drilling and fastening tasks. The set covers a wide range of applications, from drilling through metal, wood and plastic with HSS drill bits, to hammer drilling into masonry and cutting large-diameter holes up to 54mm with the included hole saws. A full selection of screwdriver bits — Slotted, Pozi, Phillips and Torx — alongside nut drivers for hexagonal fasteners makes this a genuinely capable all-round kit for electricians, carpenters and general contractors. The kit is supplied in a TSTAK-compatible storage case that slots directly into a TSTAK drawer unit, keeping all accessories organised and immediately accessible on site. The case is also fully functional as a standalone carry case, and can be stacked and transported on a TSTAK trolley. Compatible TSTAK tool boxes include the DWST1-70705, DWST1-70706 and DWST1-70702.
