Red Seal Tool and Die Maker Practice Exam

The primary function of a broach in machining is to remove material and create a specific shape or size. Broaching involves using a specialized tool called a broach that has multiple cutting edges arranged along its length. As the broach is pulled or pushed through the workpiece, it removes material in a single pass, allowing for the efficient creation of complex shapes, such as keyways, slots, and other profiles that are often challenging to achieve through conventional machining methods.

This process is particularly valued for its ability to produce precise dimensions and smooth finishes, making it an essential method in tool and die making. Broaches are designed for specific applications, and their design dictates the exact shape they will produce, making them highly effective for tasks requiring replicas or tight tolerances.
