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". ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***. on 1 April 2024* Despite the fact I don't use my drill often, any time I needed to do a job on some kind of difficult material, these drill bits have never failed me.
