Parting Tool Holder

A Parting Tool Holder is a specialized tool holder designed to securely hold a thin, blade-like parting tool (also known as a cut-off tool) used in machining operations, primarily on a lathe. Its primary function is to cut off a rotating workpiece at a desired length or to create deep, narrow grooves. The holder is engineered to provide maximum rigidity and support to the slender parting blade, which is crucial for preventing vibration and ensuring a clean, accurate cut.

These tool holders often feature unique clamping mechanisms that grip the thin blade along its length, providing the necessary stability to withstand the cutting forces involved in parting off. Some designs may also incorporate features like coolant channels directed towards the cutting edge, which helps in chip evacuation and reduces heat buildup, leading to improved tool life and surface finish.

A high-quality parting tool holder is essential for efficient and safe parting-off operations. It minimizes the risk of tool breakage, reduces chatter, and allows for higher feed rates. Choosing the right parting tool holder depends on factors such as the size and material of the workpiece, the machine tool being used, and the desired cut-off width. Ultimately, it plays a critical role in achieving precise and clean separation of material in various machining applications.
