Hydraulic chucks are effective for reaming, drilling, threading and light milling with end mills at high spindle speeds. They use oil pressure to compress an internal membrane within the holder body, uniformly applying high pressure to grip 360° around the tool shank.

A tool holder is a device that safely provides a critical interface between the cutting tool and the spindle of the CNC machine. The cutting tool is mounted into the holder and is tightened so it does not move or vibrate during machining; providing the stability you need to ensure precision cuts every time.
