* All CNC drill chucks are clamped with an Allen-T-wrench moving a bevel gear through a
bore on side of the chuck. The bevel pinion has to be actuated with a torque of 15 Nm to
create a holding torque of 40 Nm, respectively 45 Nm at the clamped tool (measured with
a clean hard metal bold). Higher torques can be reached but are not necessary for normal
use and have to be regarded as security in addition.
** The CNC drill chucks are suitable for work up to 7,000 revolutions per minute.
For work requiring revolutions between 7,000 and 35,000 per minute – for example alu- or
wood processing – the CNC drill chucks have to be balanced along the required revolu-
tions and balancing quality.
There are 2 types of drill chucks available:
1. Dry, without coolant feed
2. Central coolant feed
