A shrink-fit tool holder improves cutting performance compared to a standard collet system primarily due to its superior clamping force, concentricity, and rigidity. Shrink-fit holders work by heating the holder body, causing it to expand. The cutting tool is then inserted into the slightly oversized bore, and as the holder cools, it shrinks tightly around the tool shank, creating an extremely strong and uniform clamping force. Standard collet systems rely on mechanical compression ....
