(**) All CNC drill chucks are clamped on the side with a hexagonal T-key handle via a bevel gear (see operating instructions). A tightening torque of 8 Nm or 15 Nm on the hexagonal T-key is adequate to use the drill chuck. The holding torques that can be achieved with the CNC drill chucks provide additional safety and are not necessary for normal use. (***) The CNC drill chucks are suitable for use up to 7000 min-¹ "unbalanced”. For use at revolution speeds between 7000 min-¹ and 35000 min-¹ (e.g. when machining aluminium or in woodworking), the drill chucks must additionally be balanced in line with the balance classes - in consideration of the revolution speed and balance quality.
