Ever wondered why drill bits almost always spin clockwise? And what are those spiral grooves actually doing? In this video, we take a closer look at the surprisingly clever engineering behind the everyday twist drill. We’ll explore why most drill bits are designed for clockwise rotation, where the twist-drill design came from, how the spiral flutes help remove chips from the hole, and what happens when you spin a standard drill bit in reverse. It’s a simple tool you’ve probably used dozens of times—but its design is doing much more than it appears to.
