In the 19th century, the industrial revolution brought about significant changes in the design and production of drill bits. Advances in manufacturing techniques, such as casting and stamping, allowed for the mass production of drill bits with multiple cutting edges Advances in manufacturing techniques, such as casting and stamping, allowed for the mass production of drill bits with multiple cutting edges Advances in manufacturing techniques, such as casting and stamping, allowed for the mass production of drill bits with multiple cutting edges Advances in manufacturing techniques, such as casting and stamping, allowed for the mass production of drill bits with multiple cutting edgesdrill bits. This led to a significant increase in drilling speed and efficiency, making it possible to drill larger holes in less time.
