## Questions & Answers

**Q: Is the flat shank on all bits?**
A: The shank is round for the bits sized 1/16” to 1/8”. 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".
