Lathe tool holders, or "μανέλες τόρνου" in Greek, are devices used to securely hold cutting tools, often carbide inserts, on a lathe during machining operations. These holders are designed to position and stabilize the carbide inserts, which are the actual cutting elements, ensuring precision and consistency in cutting. Different types of lathe tool holders, such as those for turning, boring, or threading, accommodate various carbide insert shapes and sizes, making them essential for achieving high-quality machining results.
