Over time, these tools evolved into more sophisticated versions. The twist drill bit, which is widely used today, was invented in 1861 and improved cutting efficiency. In the twentieth century, the development of new materials and manufacturing processes further improved the performance and durability of drill bits, leading to the wide variety of types we see today.

To understand the context of jobber drill bits, let’s start with a brief overview of the evolution of drill bits. The history of drilling can be traced back to the ancient civilizations that used rudimentary tools made from sticks and stones.

Jobber drill bits have a longer shaft than mechanics-length drill bits, allowing them to drill deeper holes. The bit’s rigidity helps keep holes straighter, reducing runout, skating, and deflection.
