DEDRA 18A11S246 246-Piece Drill and Screwdriver Bit Set with HSS, Wood, Masonry Bits and CrV Driver Bits in Blow-Molded Case

For professionals and serious DIYers who refuse to compromise on versatility, the DEDRA 18A11S246 246-piece mixed drill and screwdriver bit set consolidates an entire workshop's worth of drilling and driving accessories into one robust blow-molded case.

• Screwdriver bits in Phillips, Pozidriv, Torx, slotted, and hex profiles, in 25 mm and 50 mm lengths.
• Includes magnetic bit holder, countersink, nut setters (5–13 mm), and depth stops.
• Robust blow-molded plastic case keeps every piece organized and protected.

In daily use

Whether you're drilling pilot holes in hardwood, driving screws into metal studs, or boring into concrete, this set has the right bit for the job. The HSS bits slice through steel and non-ferrous metals with precision, while the carbon steel wood bits feature sharpened tips for clean entry and reduced splintering. For masonry, the tungsten carbide tipped bits deliver reliable performance in brick, block, and light concrete. The screwdriver bits, forged from chrome vanadium steel, resist wear and maintain their profile even under high torque from impact drivers. The magnetic bit holder speeds up bit changes, and the included nut setters handle hex-head fasteners with ease. Depth stops on the drill bits help prevent over-drilling, a common cause of damage in finish work.
