Drills are used in a variety of manufacturing settings, including construction, woodworking, metalworking, machine tool fabrication, etc. There are also a variety of specialty drills designed for specific purposes, such as use in medical or aerospace applications.
Drills are a descendant of the first tools that implemented rotary motion to hollow out a material. It is thought that these early rotary tool relics originated around 35,000 BC. Various other drill renditions were invented in early human history, including bow drills, core drills, and pump drills.
Today, there are a variety of different drill options, including manual drills, electric drills, compressed air drills, and even internal combustion engine drills. Corded and cordless drills are the most common type of drills.
