Mandrel for drifting the casing or drill pipe is forged with high-strength alloy steel, strict heat treatment process.
The drill pipe is placed in the wellbore to make a connection at the surface, typically at the rotary table or a similar connection point. This allows for the alignment of the pipe with the floating or rig equipment, ensuring a secure and effective connection. Once aligned, the drill pipe can be threaded or mechanically locked into place to facilitate drilling operations.

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.
The drilling pipe comes in sections and they periodically stop drilling to add another section. This way they can drill to almost any depth desired. The physical drilling head on the tip of this pipe is rarely more than a couple of feet long.
A 4 inch drill pipe torque is used for fishing in small casing.

To effectively drill holes in PVC pipe for irrigation, use a drill with a sharp bit that is the same size as the desired hole. Mark the location of the holes on the pipe, then drill slowly and steadily to avoid cracking the PVC. Clean any burrs from the holes to ensure smooth water flow.
It holds the drill tube steady and is the path for oil or water to return when found.
Use 7/64 as tap drill and 9/64 as clearance drill

There is a special chuck on the lower end of the turntable that turns the pipe.
The term "tripping the well" got it's start most likely as a reference to the "round trip" made by the drill bit. The first leg of the trip is coming out of the hole, by lifting the entire drill string and unscrewing the upper most drill pipe called a joint, the newly removed drill pipe is laid beside the rig and the drill string is lifted again, etc. until all drill pipe is out of the hole. After service work is performed, for example change to fresh drill bit, then the second leg of the trip is to reverse the process, lowering the drill string as each new joint is made until fully back in the hole with the bit on bottom. You can find a lot of interesting videos on offshore rigs, jobs, etc here: I left the previous answer in place: When drill pipe is lowered or put into the well in the well, it is called running in or is tripping into the well. When drill pipe is raised or pull out of the well, it is call running out or tripping out of the well.
