There are two different types of tools to do this. Ask for a 'spade bit' or 'hole saw' at the hardware store. Either one is used with an ordinary power drill. When cutting through plastic with power tools, do not run the tool at maximum speed as the friction may melt the plastic and make the cut edge less clean.

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. :-)

How much time does it take to drill a hole?
The time it takes to drill a hole depends on the material being drilled, the size of the hole and the machine doing the drilling. But you knew that. It takes longer to chuck a bit in a drill than to actually punch an eighth inch hole through a piece of quarter inch plywood. But drilling a one inch hole through a twelve by twelve framing timber takes longer. Particularly if you're using a brace and bit.

Roll up your sleeves and make sure you have a good water supply to lubricate and cool the diamond coring bit on your rig.
