I picked up the DEWALT Drill Bit Set, 21-Piece, 135 Degree Split Point, 31 Degree Helix, Black Oxide Coated, For Plastic, Wood and Metal (DWA1181) drill bit set because I needed something reliable for my contracting work around Houston, and DEWALT has always delivered solid tools. At $19.77, it seemed like a fair price for a 21-piece set that claims to handle plastic, wood, and metal. Coming from a military background, I don’t waste time on cheap garbage that fails halfway through a job. I wanted to see if this set could live up to DEWALT’s reputation.
