Eighty pieces gives you the range to move between drilling, driving, and countersinking without digging through separate boxes for the right bit. DeWalt built this set for the drawer that gets opened every day - deck screws in the morning, a loose cabinet hinge in the afternoon, drywall anchors on the weekend.The steel construction holds up to repeated use on wood, metal, and general fastening work, and the hex shank fits standard drill/driver chucks without any adapters. Bits are magnetic, so they grab and hold screws on their own - useful for one-handed work overhead or in tight corners where a dropped screw means starting over. Everything ships in a clamshell case that keeps the assorted sizes sorted and easy to grab on the way to the job.This is a set for anyone who does enough varied work - homeowner projects, punch-list repairs, light contracting - that a single all-purpose bit just doesn't cut it anymore. 80-piece drill and driver bit set Steel construction for durability Magnetic bits hold screws in place Hex shank fits standard drill/driver chucks Assorted sizes for varied fastening tasks Clamshell packaging for organized storage
