HSK63F Hydro Chuck
3/8 in Direct Bore
Klein T518.095.N is the compact 80 mm gauge-length HydroBlock® HSK63F hydraulic chuck with a direct 9.5 mm (3/8 in) bore. It is precision balanced to G2.5 at 24,000 RPM and designed to clamp compatible cylindrical-shank tooling uniformly for high concentricity, reduced vibration, and repeatable CNC routing performance.

Main Product Description
Klein T518.095.N is the exact 80 mm gauge-length, 3/8 in bore Item in the T518 HSK63F hydraulic-chuck family. The official Item row specifies a 63 mm flange diameter, 30 mm body diameter, 50 mm outer diameter, 41 mm internal clamping length, and suitability for both right-hand and left-hand rotation.
The HydroBlock® expansion system clamps hydraulically. Tightening the supplied operating screw drives an internal piston, pressurizing the sealed oil chamber and expanding the clamping sleeve evenly against the tool shank. This uniform contact is designed to improve holding force and concentricity while reducing vibration during routing.
SISTEMI publishes concentricity of ≤ 0.005 mm and precision balance grade G2.5 at 24,000 RPM for the T518 family. The hollow taper is produced to DIN 69893, and the installed cutting tool must have a cylindrical h6-tolerance shank. A hexagonal T-key is included for the clamping operation; compatible Klein T521 reduction sleeves may be added separately when another supported shank diameter is required.

Product Highlights
Hydraulic Holding Precision
02
G2.5 High-Speed Balance
Precision balanced to grade G2.5 at 24,000 RPM for compatible CNC routing applications where vibration control and repeatability matter.
03
Compact 80 mm Format
The compact A=80 mm body provides direct 3/8 in clamping while maintaining HSK63F spindle compatibility and RH/LH rotational use.
Compatibility & Installation Notes
Confirm an HSK63F spindle interface before installation. Clamp only compatible cylindrical tool shanks with h6 tolerance and a nominal 9.5 mm (3/8 in) diameter unless an officially compatible Klein T521 reduction sleeve is installed. Insert the tool to the specified clamping depth, keep the bore and shank clean and dry, and operate the hydraulic clamping screw with the supplied T-key according to SISTEMI instructions. This holder supports right-hand and left-hand rotation; do not exceed the published G2.5 balance condition of 24,000 RPM. Cutting tool, reduction sleeve, and demount device are separate unless specifically included by Titan.
HydroBlock® Toolholding
Precision Grip With Less Vibration
Klein T518.095.N combines an HSK63F interface, compact 80 mm gauge length, direct 3/8 in bore, and uniform hydraulic expansion for accurate cylindrical-shank clamping on compatible CNC machining centres.
Its published ≤ 0.005 mm concentricity, G2.5 balance at 24,000 RPM, RH/LH capability, and included T-key make it a focused toolholding solution for repeatable routing setups and finish-sensitive production work.
