Drilling a triangular hole isn’t possible with a standard round drill bit, but it can be done using a special method involving a Reuleaux triangle. This is a shape with curved sides that allows for a constant width, making it possible to drill a triangular hole using a rotating bit. To do this, you need a Reuleaux triangle drill bit and a custom jig that guides the bit in a specific, off-center motion. When used with a drill press, the jig forces the bit to wobble in a precise pattern, gradually

explaining.science on Instagram: "Did you know you can drill a triangular hole—without ever using a triangular drill bit? 🤯 Engineers use a fascinating mathematical shape called the Reuleaux Triangle, which rotates inside a square or circular boundary while maintaining a constant width. When a specially designed drill spins this shape, its path carves out a near-perfect equilateral triangle. This technique blends geometry + engineering innovation, allowing machines to create shapes that seem im
