What is the name for a multi-point cutting device that can perform rough cutting operations?

The correct term for a multi-point cutting device that can perform rough cutting operations is a saw. Saws in metal cutting contexts often feature multiple teeth or cutting edges, enabling them to remove material quickly and efficiently, making them suitable for rough cutting tasks. They work by using the teeth to cut through the material, which allows for significant material removal in a single pass.

While drills, tool bits, and chisels are essential cutting tools, they serve different purposes. A drill is primarily designed to create round holes and typically has a single point or a small number of cutting edges rather than multiple. A tool bit, which is often used in lathes and milling machines, typically has a more precise cutting edge meant for finishing operations or cutting in a specific pattern. Additionally, a chisel is a single-point cutting tool best suited for shaping and can perform finer tasks rather than rough cutting across larger areas. Thus, the saw is the most fitting answer for a tool designed for rough cutting with its multi-point design.
