9 - 1 How to Replace Collets using the Provided Wrenches
(1) Attach the collet to the collet nut. Be sure to fully engage the latch inside the collet nut
to the groove on the collets outer circumference area (Fig. 5, Fig. 6) (Install the collet
in the collet nut by positioning the collet in the collet nut and pressing down on
À
at
surface (Fig. 7)).
(2) Attach the collet and collet nut to the collet holder and lightly
¿
nger tighten.
(Do not completely tighten until the end) (Fig. 8).
(3) Insert the tool in to the collet and position the wrench on the collet holder.
Position the wrench on the collet nut, then tighten the collet nut by turning clockwise
(Fig .9).
(4) When removing the tool, set the wrench on the collet nut and turn it counterclockwise
to loosen the collet and remove the tool (The
¿
rst turn will loosen the collet nut,
but the tool will not release and turning will become stiff. Keep turning through the
stiffness and the collet will open.).
(5) When removing the collet, the collet and collet nut are secured by a groove in the
collet and a
À
ange in the collet nut. To remove the collet hold the collet nut in one
hand and push diagonally down on the collet. The collet should be released (Fig. 7).

CAUTION
・
Do not tighten the collet without inserting a tool or dummy bur, as this will
damage the collet, collet holder or collet nut, causing dif
¿
culty removing
the collet.

When installing the collet in the collet nut, make sure to fully engage the
latch inside the collet nut to the groove on the collets outer circumference
area. In addition, remember that if the collet is attached without being
engaged with the latch of the collet nut, the collet cannot be removed and
this may cause damage to the collet or the collet holder.
RECOMMENDATION
Please minimize the tool overhang amount to maintaining high accuracy.
