The spelling of the word "drilling" can be explained with the IPA phonetic transcription, which is /ˈdrɪlɪŋ/. The first sound, /d/, is made by placing the tip of the tongue against the alveolar ridge and releasing a burst of air. The following sound, /r/, is made by vibrating the tongue against the alveolar ridge. Next, the short vowel sound /ɪ/ is pronounced with the tongue more or less in the center of the mouth. The final sound, /ŋ/, is produced by the back of the tongue touching the soft palate.
Drilling refers to the act or process of creating holes or cavities in a material typically using a rotating cutting tool known as a drill bit. It is a fundamental machining operation employed in various industries and applications, including construction, manufacturing, mining, and exploration.
In drilling, the drill bit is pressed against the workpiece while being rotated, allowing it to remove material and form a hole. This hole can have various purposes, such as accommodating fasteners like screws or bolts, creating space for wiring or plumbing, or extracting subsurface resources like oil, gas, or minerals. Drilling is commonly performed on materials like metal, wood, concrete, plastic, and rock, with specialized drill bits designed for specific materials.
Drilling can be carried out using handheld drills, drill presses, or advanced machinery, depending on the size and complexity of the task. Different drilling techniques exist to meet specific requirements, including twist drilling, gun drilling, spot drilling, reaming, counterboring, and countersinking. Additionally, drilling operations often involve the use of coolants or lubricants to optimize cutting efficiency and extend tool life.
The precision, speed, and accuracy of drilling greatly depend on factors such as the type of drill bit, cutting speed, feed rate, and the rigidity of the machine setup. Additionally, proper operator skill, safety precautions, and adherence to drilling guidelines are essential to ensure successful and efficient hole creation while minimizing risks and accidents.

The word "drilling" derives from the Middle English term "drillen", which initially meant to pierce or bore a hole. It can be traced back to the Old English word "driellan", which had a similar meaning. The Old English term itself derived from the Proto-Germanic root "drailijaną", meaning "to pierce" or "to drill". This root is also connected to words in other Germanic languages, such as Old Norse "drīla" and Middle High German "drīlen". Ultimately, the origin of the word can be traced back to the Proto-Indo-European root "*terh₁-", meaning "to rub, pierce".
