With the Dewalt DT7926-XJ metal drill bit set, you drill with instant precision through alloyed and non-alloyed steel, sheet metal, wood, and plastic. Thanks to the pilot tip, each bit starts immediately on contact to prevent walking, making center punching unnecessary. Recessed cutting wings produce clean, smooth, and burr-free holes, while the tapered core significantly increases durability to resist snapping under pressure. Furthermore, the 3-flat shank on bits 5 mm and above prevents slipping inside the drill chuck. Containing 29 bits from 1 mm to 13 mm including intermediate sizes, this robust Tough Case keeps all your essential drill bits organized and protected.
