An HSK-F 63 Hydro Chuck is an easy way to improve tool life and reduce tooling cost on the tool that is your shop’s “work horse”. While heat-shrink and power shrink tool holders equally improve accuracy and increase tool life, the investment in additional accessories required to mount and remove the tool from the holder often makes it cost prohibitive for the smaller shop, if the need to remove the tool from the tool holder for sharpening becomes necessary. The only time this is not a problem is with insert tooling or diamond tooling. To achieve best accuracy with solid carbide bits, for instance, an HSK hydro clamping chuck would be a great alternative. Precision balanced to 25,000 rpm, the tempered and ground tool holder will provide higher clamping precision than a standard collet and nut are able to, since it grips the tool shank absolutely concentrically over the full length of the tool shaft.

The use of an HSK-F 63 hydro chuck will improve tool life (less compounded tolerances from collet and nut) as well as the 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 in 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.  They are great choices for cutting composites and other materials that require a precision machining environment to optimize tool life.
