What is a multi-point cutting tool that can remove metal and finish a surface with one pass?

A multi-point cutting tool designed to remove metal and finish a surface in a single pass is known as a broach. Broaching is a machining process that involves the use of a broach, which has multiple cutting teeth arranged along its length. As the broach is pulled or pushed through the workpiece, these teeth sequentially engage the material, gradually removing it until the desired shape and finish is achieved.

Broaching is particularly effective for creating complex profiles, such as gears or keyways, with high precision and a good surface finish. The design of the tool allows it to remove substantial amounts of material efficiently while also finishing the surface in one operation, which is a significant advantage over processes that may require multiple stages.

In contrast, the lathe and drill bit are examples of single-point cutting tools, typically used for operations that remove material in a different manner. An end mill, while also capable of multi-point cutting, doesn't typically produce the same types of finished features in one pass as a broach does, since it is often used for milling operations that might require additional steps for finishing.
