Mandrel for drifting the casing or drill pipe is forged with high-strength alloy steel, strict heat treatment process.
If you mean drill horizontally through the dirt,, I'm no engineer but fitting a length of pipe with a water tap then extend the pipe as the water washes away the dirt from the working end under the slab and flushes out the sediment seems like it would work.
For drilling in a lathe, "Drill Sleeves" also known as "Drill Quills" are used and they are set into the tail stock quill for drilling operations.
Before the electric drill , it was done by hand. There's a hand-cranked drill, probably still used by the Amish. My father owned one.
A 4 inch drill pipe torque is used for fishing in small casing.

It is a rod called the Kelly or Grief Stem.

No...what in the world would possess a man to think that explosives would be safe to use on an oil well. The proper way to drill an oil well would be to use a "Drill Bit" followed by a series of tools and special pipe to make up the "Bottom hole assembly" or the BHA. As the bit drills deeper a series of pipe are added to the top of the drilling pipe, these are call "Drill Pipe"

Oil is extracted through drilling a well into an underground reservoir, typically using a drill bit attached to a drilling rig. The oil is then pumped or flows to the surface through the well. Various techniques such as primary, secondary, and tertiary recovery methods are used to extract the maximum amount of oil from a reservoir.
Wrong Question... You first determine the hole size required for the mine plan and then based on the air capacity and pulldown capacity of the drill rig you can determine the optimal drill pipe diameter to achieve productivity from the drill. What size is your drill? Air Capacity in CFM, Pulldown Capacity. What size does your drilled hole (diameter and depth) need to be to suit the mine plan (for the drill & blast process)?
