Extension Cords
If an extension cord is necessary, a cord
with adequate size conductors that is
capable of carrying the current necessary
for your tool must be used. This will prevent
excessive voltage drop, loss of power or
overheating. Grounded tools must use 3-wire
extension cords that have 3-prong plugs and
receptacles.
NOTE: The smaller the gauge number, the
heav i er the cord.

WARNING
The number and variety of accessories for the
Rotary Tool are almost limitless. There is a
category suited to almost any job you might
have to do — and a variety of sizes and shapes
within each category which en ables you to get
the perfect accessory for every need.
Collets
If you expect to use a variety of accessories,
we recommend that in the beginning you
purchase a complete set of four collets. Store
these so that you will have the proper size of
collet for any accessory or drill bit you want to
use. Currently, the 1/8", 3/32",1/32" and
1/16" collets accommodate all of the avail -
able Dremel accessories. 1/8" collets are
included in most rotary tool kits.
Mandrels
A mandrel is a shank with a threaded or screw
head, which are required when you use
polishing accessories, cutting wheels, sanding
discs, and pol ish ing points. The reason
mandrels are used is that sanding discs,
cutting wheels and similar accesso ries must be
replaced frequently. The mandrel is a per -
manent shank, allowing you to replace only the
worn head when necessary, thus saving the
expense of replacing the shaft each time.
