How do you drill a five sixteenth inch hole four inch depth flat bottom hole?
5/16 hole X 4 inch on a flat bottom hole: This will depend on the material, and tools available. Use a 1/8 bit, then 5/16. If you are not sure how deep the drill bit is in the hole, paint white out on the bit as your 4 inch mark so you can see it while the drill is spinning. If the material is metal, you will need coolant. To get the flat bottom: it wood, put a flat ended bolt into the hole and hammer, it will flatten the hole, it metal, forget about it, the hole is quite flat, and a pain in the butt to change. :-)
