A collet is an interchangeable slotted cylinder
inserted tightly into the interior of a handpiece to
hold a bur or other rotary accessory. The diameter
size of the collet must match the diameter of the
accessory’s shank.
General Directions: Be sure to use the correct
shank size. The correct shank will fit snugly inside
the collet. Caution: Never tighten a collet unless
an accessory has been inserted. Tightening an
empty collet or inserting an accessory which is too
small or too large may damage the collet.

To change a collet: slide back the chuck guard and
use one wrench to hold the spindle and the other to

place and tighten chuck nut with wrenches.
To insert accessory: insert shank as far as possible
into the collet. Tighten chuck nut. Test for a secure
hold by pulling on accessory. Remove wrenches.
To release an accessory, follow the same steps.
