Collet Sizes
Your rotary tool kit includes four
collets to accommodate
different accessories with
varying shank sizes. To change
a collet:
1 Loosen the collet nut as
described above, then
remove the collet nut.
2 Remove the old collet.
3 Insert the loose collet.
4 Tighten the collet nut as
described above.
Each collet has a series of rings
on its shank that identify its size.
The collet sizes included with your kit are:
1/32” - one (1) ring
1/16” - two (2) rings
3/32” - three (3) rings
1/8” - no rings
Balancing
For best results, be sure to balance each accessory in the collet. Your tool’s
high RPM makes imbalances easily detectable as a wobble while the tool is
running. To balance an accessory:
1 Stop the tool.
2 Loosen the collet nut.
3 Rotate the accessory 1/4 turn.
4 Tighten the collet.
5 Run the tool.
6 Continue adjusting as needed. You will hear and feel when the
accessory is properly balanced.
