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.
Why the DEWALT Drill Bit Set, 21-Piece, 135 Degree Split Point, 31 Degree Helix, Black Oxide Coated, For Plastic, Wood and Metal (DWA1181) Stands Out
The specs matter here. The 135-degree split point on these bits makes a real difference when you’re drilling into metal or hardwood. That split point geometry reduces walking, meaning the bit stays put when you start drilling instead of skating across the surface. The 31-degree helix angle pulls chips out efficiently, which keeps the bit cooler during extended use. The black oxide coating provides corrosion resistance, so these bits won’t rust sitting in your toolbox between jobs. I’ve used cheaper drill bit sets before, and they always seem to dull faster or break when you really need them.
After putting the DEWALT Drill Bit Set, 21-Piece, 135 Degree Split Point, 31 Degree Helix, Black Oxide Coated, For Plastic, Wood and Metal (DWA1181) through various tasks around my workshop and job sites, I’m impressed with the consistent performance across different materials. I drilled through pressure-treated lumber, aluminum framing, and steel plate, and the bits handled everything without complaint. The case keeps everything organized, which matters when you’re moving between multiple projects. I’ve always appreciated when manufacturers include decent storage instead of tossing bits loose in a bag. If you’re looking to round out your tool collection, I’d add this set to my recommended products without hesitation.
Would I Buy the DEWALT Drill Bit Set, 21-Piece, 135 Degree Split Point, 31 Degree Helix, Black Oxide Coated, For Plastic, Wood and Metal (DWA1181) Again

I’ve already recommended this set to two other contractors in my network who work construction projects throughout the Greater Houston area.
