Introduction
What is a Shrink Fit Tool Holder?
A shrink fit tool holder is a type of tool holder that is designed to hold cutting tools in place during machining operations. It is made up of two parts: the holder body and the collet. The holder body is made of high-quality steel that is heat-treated to make it strong and durable. The collet is made of a special alloy that has unique thermal properties. The collet is inserted into the holder body and is heated using an induction heater. When the collet reaches a certain temperature, it expands and tightly grips the cutting tool.How does a Shrink Fit Tool Holder Work?
