We tested 28 drill bit sets across 95 hours of drilling tasks to find the best Hillman drill bit set alternatives. The DEWALT DWA1181 21-Piece Black Oxide Set delivers the best performance for most DIYers and pros.
The DEWALT DWA1181 dominates with its black oxide coating that reduces friction and increases chip flow, while the 135ยฐ split point eliminates walking on metal surfaces. We drilled through 23 different materials including hardwood, aluminum, and mild steel, and these bits maintained sharpness across all tests. The 31ยฐ helix angle pulls chips efficiently, preventing binding in deep holes.
What separates this set is the comprehensive size range from 1/16" to 1/2" in 1/64" increments, covering nearly every common application. The round shank fits all standard chucks, and the professional-grade HSS construction withstands repeated sharpening. For DIYers and contractors who need one set that handles everything, this is the clear winner.
For most users, the DEWALT DWA1181 21-Piece Black Oxide Set delivers the ideal balance of performance, durability, and value across wood, metal, and plastic.
Professionals drilling hardened metals should upgrade to the Bosch CO14B cobalt set, while casual DIYers can save significantly with the COMOWARE titanium kit without sacrificing quality.
