DeWalt 40 Piece Steel Bit Set

This DeWalt bit set contains 40 steel pieces supplied in a 12 pack arrangement. The black finished bits are designed for versatile fastening tasks across workshop and job-site applications. Part number 21 identifies this specific kit configuration. The set weighs 6.7 pounds and includes batteries for cordless operation.

Upgrading from limited bit collections

Users moving up from small starter kits gain a broader range of drive sizes and profiles in one organised package. The jump is worth it when projects regularly demand different fastener types and you want to avoid hunting for individual bits. The 12 pack format keeps compatible pieces together for quick access.

Check your drill chuck and fastener types

Verify that your drill or driver accepts the shank style used in this set before ordering. Confirm the bit profiles match the screw heads you encounter most often. The 6.7 pound weight means the case is substantial, so ensure you have storage space for the full 12 pack.
