What are the terms used in hand drilling?

In hand drilling, several key terms are commonly used, including "bit," which refers to the cutting tool used to create holes; "chuck," the part that holds the bit in place; and "feed rate," the speed at which the drill is advanced into the material. Other important terms include "torque," which measures the twisting force applied, and "depth of hole," indicating how deep the drill penetrates. Understanding these terms is essential for effective hand drilling techniques.
