Machining tools are unlike hand tools in that multiple parts are necessary for them to function, and assembling them correctly is paramount for these tools to work properly and perform the functions they must perform. Often, these machining tools are housed in tool holders, which keep all necessary parts together in separate components, making it easy for someone to reach for the pieces needed for any particular task.

Tool holders too are increasingly used in high velocity applications that are more dangerous in nature, thereby requiring that whatever pieces are put together for a tool are accurate. This includes CNC machining tools, which use programs to execute machining operations automatically. Even though these tools are automated, they still have parts and a tool holder still proves valuable. These tool holders hold other important tools too, like a box tool, which is mounted onto a turret part of a lathe or a screw machine, and a toolpost, which is part of a lathe for metal working that holds a tool bit in place or that holds the actual holder of tools with the tool bit in it.

These tool holders hold all valuable components of tools, making them accessible when needed and easily stored away when not in use. These tool holders additionally keep all components safe and free from getting damaged or becoming lost or stolen. Through keeping these valuable parts in these holders, machinists and others have a singular, affordable place to turn when these tools are required.
