Lathe tool holders are devices used for the secure mounting of 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 main cutting elements, ensuring accuracy and consistency in cutting. Various types of lathe tool holders, such as those for turning, drilling, or threading, support different shapes and sizes of carbide inserts, making them essential for achieving high-quality machining results.
