CHANGING THE TOOL

7.

Do not tighten the collet without inserting a tool or dummy bur, as this will damage the collet, spindle 
or collet nut, causing difculty removing the collet.

 

 CAUTION

Please set the cutting tools to minimize the overhang amount. 13mm is the maximum amount of 
overhang to maintain high accuracy and safety.

RECOMMENDATION

Set the provided 12mm wrench on the spindle.

Place the provided 14mm 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).

Clean the collet and collet nut, then insert the new 
tool and tighten the collet by turning clockwise. Do 
not overtighten.

REPLACING THE COLLET

8.

When installing the collet into the collet nut, be sure to fully engage the latch inside the collet nut 
to the groove on the collets outer diameter 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 spindle. 

 

 CAUTION

Remove the tool according to the section 
" 7. CHANGING THE TOOL " procedure above 
and remove collet nut assembly (Fig. 4).

The collet and collet nut are secured by a groove 
in the collet and a 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. 5).

To install the collet, hold the collet at a slight angle, 
and insert it into the collet nut (Fig. 6).
Press the collet in the collet nut by positioning the 
collet in the collet nut and pressing down on at 
surface (Fig. 5).
Be sure to fully engage the latch inside the 
collet nut into the groove on the collet's outer 
circumference area (Fig. 7).
