True-running accuracy 3 μm incl. clamping nut

Precision ER collet chuck

• 30° ground trapezoidal thread with special anti-friction coating
• Up to twice the holding forces of conventional collet chucks are possible thanks to lower friction when tightening the nut and due to the collet being seated entirely inside the chuck cone.
• Resistant to temperature fluctuations and fully suitable for dry processes and hard milling up to 200 °C.
• Clamping forces are distributed evenly across the entire cylindrical surface, and optimum radial force absorption produces perfect surfaces
• Excellent damping properties
• Increasing the chuck body to the diameter of the clamping nut creates enormous stability without any protruding contours.
• Extremely high concentricity and precision, 3 µm
• Pre-balanced to G 2.5 at 22,000 rpm
• Leak-proof up to 80 bar with radially sealed collets
• For all GER collets
• Supplied with clamping nut
• Please order roller chuck key separately
  Torque wrench recommended

DIN ISO 7388-1 / DIN 69871 AD, incl. clamping nut

• Internal coolant supply
