4.10.2 Removing

Hold the spindle on counter bearing with a wrench and loosen the draw bar. Continue turn-
ing the tie rod, so that the tool is squeezed out from the conical seat.
ATTENTION!
When installing a cold morse taper into a heated-up machine those MT seats tend to
shrink on the morse taper contrary to the steep cone connection.
4.10.3 Use of collets
If collets are used to house milling tools, higher machining tolerance can be achieved. The
collet may easily and quickly be changed for a smaller or larger end mill with no need to remove
the complete tool. The collet is pressed into the ring of the swivel nut and must rest there by
itself. By tightening the coupling nut on the tool, the milling cutter is clamped centrally. Make
sure that the correct collet is used for each end mill diameter, so that the milling cutter may be
fastened securely and firmly.
