A twist drill is basically a cylindrical piece of steel with special grooves. One end of the cylinder is pointed and the other end is so shaped that it can be attached to the drilling machine. The grooves are usually called flutes. The flutes formed by twisting a flat piece of steel into a cylindrical shape and such types of cylindrical shape drills are called twist drills.

The term “drill bit” is limited to bits that fit into your power drill and drill holes. These are different from “driver bits” which fit into your drill and work as the power tool version of a screwdriver. It’s an easy mistake to refer to both groups as drill bits, but knowing the difference will not only help bring clarity to you and the people you’re talking to, but it will also make you look like you know what you’re talking about. The key to remembering the terms is to attach the appropriate verbs: a driver bit drives screws, while a drill bit drills holes. 

The most standard, go-to drill bit for drilling wood, plastic, and even metal, is a twist drill bit. Just like the threads of a screw help it grip into the wood, the grooves of a twist drill bit allow it to glide through your material more easily and create a way for the shavings to escape as you drill.
