HSK hydro tool holders offer the same high precision clamping tolerance of heat shrink tool holders, without the additional investment in a heat induction unit. Precision balanced to 25,000 rpm, the tempered and ground tool holder provides higher clamping precision than a standard collet chuck (.003mm versus .006-010mm of standard chucks).
The use of a hydro clamping chuck will improve tool life (less compounded tolerances from collet and nut) and will 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 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 for maximum performance.
