What size drill bit for a 14mm tap?
One of my boys, Quantis, is looking to start making some homemade supressors, I got him the 1.5" aluminum bar stock, figured I'd slice it and have it bored for him since he has little in the way of metal working tools. I don't have a tap to go by, so I figured I'd ask on here so I can tell the machinist what size bit to use to bore it properly, then I'll cut the slices.
Thanks
