HPH high-performance HYDRO expansion chuck (ISO 7388-2)
Short, heavy-duty design

BT Form G 2,5 < – 0,003 ISO
40 IK JD/JF 25000 rpm 7388-2
Application: Advantage:
For high-precision and centric clamping of milling, ƒ Sturdy version ideal for HPC+HSC metal cutting
drilling and reaming tools – particularly with milling ƒ Damping properties to increase tool duration and
and heavy-duty machining during rough machining. service life of machine spindle
Execution: ƒ Vibration-damping effect reduces micro-cracks
and improves the workpiece surface
ƒ With axial longitudinal adjustment ƒ All common shanks can be clamped (Ø tolerance
ƒ Reducing sleeves for flexible applications h6)
ƒ Very high concentricity (< 3 µm) ƒ Very high torque transfer (Ø 20 = 650 Nm) A
ƒ Coolant pressure up to 80 bar
ƒ Heat-resistant up to 100°C Notes:
The previous standard DIN 69871-1 was replaced by d D
ISO 7388-1.
