A typical hole cutter drill bit consists of a circular blade with teeth on the perimeter, a pilot drill bit at the center, and often a shank that connects it to the drill. The pilot bit helps guide the hole cutter, ensuring a straight and accurate cut, while the sharp teeth on the circumference do the actual cutting. The design allows for faster removal of material, reducing the time and effort required compared to other drilling methods.
