What is a "countersink bit"?

A countersink bit is a type of drill bit used to create a tapered hole, allowing the head of a screw to sit flush with or slightly below the surface of the material. It is commonly used in woodworking, metalworking, and construction to ensure screws are properly seated and do not stick out. The bit's angled edges allow it to create the tapered hole needed for the screw’s head to fit neatly, providing a smooth and professional finish to the project.
