In machining, the primary function of a toolholder is to secure cutting tools during operations. A toolholder provides a means to firmly grip the cutting tool, ensuring it remains stable and properly aligned throughout the machining process. This stability is crucial for achieving precise cuts, maintaining tolerances, and ensuring safety while the machine operates.

The design of toolholders allows for quick installation and removal of tools, along with the capacity to handle various sizes and types of cutting tools, such as end mills, drills, and inserts. Without a secure toolholder, the cutting tool could move or disengage, leading to poor machining results and potential damage to both the tool and the workpiece.

Other options, while relevant to various aspects of machining, do not describe the primary role of a toolholder. Lubrication, sharpening, and transportation of tools are important processes in the overall machining workflow, but they do not define the essential purpose of a toolholder, which is fundamentally about securing tools in place during the cutting operation.
