Table 13: Maximum permitted cutting force
On extended chuck versions, the ratio of maximum permitted
cutting force to chuck lengths needs to be reduced. For ex-
ample, size 32 with �� = 150����

With drilling operations radial to the workpiece axis, the feed
force of the tool generates transverse forces that ultimately
act on the clamping head chuck. The application of this load
during drilling operations should be viewed as equivalent to
the cutting force exerted by a turning process. Accordingly,
it also has to be limited. Consult the following table for the
permitted maximum values.
