Characteristic

Model : 5X5HSK

The HSK series spindle grippers are engineered for high-speed, high-precision machining applications, compliant with international HSK standards. Featuring a dual-stage expansion structure and high rigidity design, they ensure excellent clamping force and stability even at ultra-high spindle speeds.

Designed for standard HSK tapers (E, A, B, C types)
Available in black coated versions for minimum friction and extended lifetime
Dual expansion stages for superior tool stability and positioning accuracy
Maximum spindle speed supported up to 80,000 RPM (E25)
Short clamping stroke, quick response ideal for ATC systems
