What is the additional part of a tool bit, made of a tool blank, along with face, nose, and shank?

In the context of a tool bit, the additional part that is referenced as being made from a tool blank, alongside the face, nose, and shank, is known as the base. The base serves as the foundation of the tool bit, providing structural integrity and stability during machining operations. It is critical for proper attachment to the tool holder and ensuring that the cutting edges perform effectively. This part also contributes to the overall shape and design of the tool bit, allowing it to be optimized for specific applications.

The face, nose, and shank are essential components as well, each having specific functions in the cutting process. The face is generally the part where the cutting action occurs, while the nose is the point where the cutting edges converge, and the shank connects the tool bit to the machine. However, without the base, the functionality and effectiveness of the tool bit could be compromised, making it a fundamental part of the overall design.
