Use of collets
If collets are used to house milling tools, higher machining tolerance can be achieved. The col-
let 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. The milling cutter is clamped by fastening the swivel nut on the tool. Make sure that the
correct collet is used for each milling cutter diameter, so that the milling cutter may be fastened
securely and firmly.

Clamping the workpieces
CAUTION!
Injuries can be caused by parts flying off.
The workpiece must always be secured to the milling table in a machine vice, chuck or
with another suitable clamping tool, such as clamping claws.
