They work about 600 feet underground, with the shriek of the huge metal drill boring through bedrock, and with the knowledge that the bedrock overhead may collapse at any time.
Mansfield exemplifies this mood when he writes: "Make one big kinetic sculpture: bellows huffing, anvil singing, dentist's foot-treadle drill boring into enamel and pulp, huge bandsaw cutting into oak, taps and dies spinning through metal blocks leaving curling metal shards".
It's like the point on a drill, boring deeper and deeper as she rants about a young woman's promiscuity (her own, perhaps), the passing of time, the smallness of the world (or is it the smallness of her mind?), and her faith in God.
Increasingly sophisticated sensors provide hundreds of calculations per minute as a drill bores ahead, dictating the angle at which to adjust the bit in order to maintain a graceful curve that won't kink the pipe.

Internal cylindrical operations include most of the common hole-machining operations, such as drilling, boring, reaming, counterboring, countersinking, and threading with a single-point tool or tap.
A variety of turning, drilling, boring, reaming, and thread-cutting tools can be fastened to the main turret, which can be rotated intermittently about its vertical axis with a hand wheel.
An important task given during the work is to create the systems of flow paths inside the body, which are assumed to be performed with simple technologies like: drilling, boring and milling.
The land was scarred, the air was filled with the incessant shriek of drills boring a mile or more into the earth, and, in a singularly grievous affront to Ken and his neighbors, the clean mountain water locals pulled from their wells was now tainted by methane.
Reamer, rotary cutting tool of cylindrical or conical shape used for enlarging and finishing to accurate dimensions holes that have been drilled, bored, or cored.
Dozens of workers — some wielding pickaxes, others driving mechanized trucks with electric drills — bored holes and inserted sticks of dynamite to dislodge lead and zinc deposits.
