cap counter clockwise to loosen the collet
nut. Do not engage the shaft lock while
the tool is running.

DREMEL CHUCK 4486
The Dremel chuck allows you to quickly and
easily change accessories on Dremel tools
without changing collets. Accepts accessories
with 0.8 - 3.2 mm shank.
To loosen, first press shaft lock button and
rotate the shaft by hand until it engages the
shaft lock. Do not engage the shaft lock
while the tool is running.
With the shaft lock engaged use the wrench
or the EZ Twist nose cap to loosen the chuck
and open the jaws.
Remove the accessory from the chuck. If
necessary, continue loosening the chuck
so that the new accessory fits between the
jaws. Insert the new accessory into the chuck
far enough so that there is approximately
6 mm between the end of the chuck and
the beginning of the working part of the
accessory. With the shaft lock engaged,
tighten the chuck using the EZ Twist nose
cap or wrench to secure the accessory.
HELPFUL TIPS WHEN USING THE
DREMEL CHUCK
• The Dremel chuck and the collet and
collet nut system are interchangeable on
this tool. While the chuck will provide you
with the best experience for changing
accessories, the collet and collet nut will
provide a more precise accessory holding
solution especially in heavier side load

applications.
• If you find the accessory slipping in the
chuck, use the included EZ Twist nose
cap or wrench to tighten the chuck
around the bit. If further slippage persists,
switch to using the collet and collet nut.
• The jaws of the chuck can become
displaced causing the accessory to no
longer run true and concentric (run-out).
To reset the jaws, apply the following
procedure:
1. Remove the accessory from the chuck.
2. Clean the chuck.
3. Press shaft lock button and tighten the
chuck until the jaws extend past the
outer surface of the chuck, approximately
3 mm.
4. Push the end of the chuck firmly against
a hard flat surface to be sure the jaws
are all seated axially.
5. Continue to hand tighten the chuck until
the jaws completely close.
6. Loosen the chuck, and reinsert a straight
accessory.
7. Turn the tool by hand and observe if
there is any runout. If there is obvious
run-out, repeat the procedure.
8. With the shaft lock engaged, tighten
the chuck using the EZ Twist nose cap
or wrench to secure the accessory.
9. Turn the tool on to the lowest speed
setting and observe for run-out. If there is
obvious run-out, check that the accessory
is straight before repeating the procedure.
BALANCING ACCESSORIES
For precision work, it is important that all
accessories be in good balance (much the
same as the tires on your automobile). To
true up or balance an accessory, slightly
loosen collet nut and give the accessory or
collet a 1/4 turn. Re tighten collet nut and
run the rotary tool. You should be able to tell
by the sound and feel if your accessory is
running in balance. Continue adjusting in this
fashion until best balance is achieved.
