For bits sized 13/64” to 1/2”, they have the three flat shank. **Q: Will these drill thru stainless?** A: YES. The DWA1181 DEWALT 21-pack black oxide twist drill bit set is ideal for general-purpose drilling materials like metal. It’s no secret that stainless steel is in fact a metal. I’ve used the 9/16” version (not included in this set, but exact same parabolic flute 31 degree helix design) to drill perfect holes in very hard 1/4” thick stainless steel. Use a drill press, not a hand held drill, go slow and use a good lubricant like Anchor. The bit cuts very smoothly and the resulting hole is smooth and shiny inside. Just my 2 cents. **Q: are these 1/4 inch hex** A: These are 1/2 drill bits. **Q: Are these universal? Do they fit most drills?** A: Yes, the largest drill bit shank in the DWA1181 is a 1/2". ## Frequently Bought Together - DEWALT Drill Bit Set, 21-Piece, 135 Degree Split Point, 31 Degree Helix, Black Oxide Coated, For Plastic, Wood and Metal (DWA1181) - DEWALT Screwdriver Bit Set, Impact Ready, FlexTorq, 40-Piece (DWA2T40IR) - DEWALT 20V MAX Cordless Drill and Impact Driver, Power Tool Combo Kit with 2 Batteries and Charger (DCK240C2) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/314046508-dewalt-drill-bit-set-21-pc-high-speed-steel-dewalt](https://www.desertcart.ro/products/314046508-dewalt-drill-bit-set-21-pc-high-speed-steel-dewalt) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-14*
