Guhdo 6390.953.00 – HSK63F Hydro Chuck for 3/8“ Diameter Shank Tools

The use of a hydro clamping chuck will improve tool life (less compounded tolerances from collet and nut) as well as provide a better surface finish. The chuck features a hexagon screw that, when installing a tool, is tightened to the “stop” point. The clamping piston forces the hydraulic medium into the expansion chamber to increase pressure, which first centers the tool shaft and then tightens it securely and accurately for a very solid and secure connection. An excellent choice for cutting composites and other materials that require the highest precision machining environment.
