Drilling is a process used to create holes in various materials, such as wood, metal, or rock. It involves using a tool called a drill, which rotates a drill bit to cut through the material. Drilling is commonly used in construction, manufacturing, and mining to install fixtures, extract resources, or create pathways. There are different types of drilling techniques, including rotary drilling, percussive drilling, and core drilling. Each method is suited for specific applications and materials. For example, core drilling is often used in geological studies to obtain samples from the earth, while rotary drilling is frequently employed in oil and gas extraction.
