Tool holders for lathes are essential components that securely hold cutting tools in place during machining operations. They come in various shapes and sizes, designed to accommodate different types of tools, such as drills, end mills, and turning tools. Proper tool holders ensure precision and stability, allowing for accurate cuts and finishes on materials like metal and wood. These holders can be made from materials like steel or aluminum and often feature a clamping mechanism to keep the tool firmly in position. Common types include collet chucks, tool posts, and quick-change holders, each serving specific applications in the lathe machining process.
