What is the purpose of multi-point tools in machining?

The purpose of multi-point tools in machining is to remove material using multiple cutting edges, which allows for more efficient material removal compared to single-point tools. These tools are designed to distribute the cutting forces across several edges, enabling them to handle larger volumes of material and achieve higher feed rates. The use of multiple cutting edges also leads to improved tool life, as the wear is spread out among the different edges, reducing the stress on any single cutting edge.

Multi-point tools are commonly found in various machining operations, such as milling and drilling, where they can effectively engage with the workpiece and create the desired shape or finish. This capability is particularly beneficial when machining materials that require higher cutting rates and improved productivity in manufacturing processes.
