Collets (_=====__

purchase a corn plate set of four cotlets. Store
these so that you will have the proper size of
toilet for any accessory or drill bit you want to
use. Currently, the 1/8" and 3/32 n collet_
accommodate all of the available Dremel
accessories.
Mandrels
A mand rei is a shank with a threaded or screw
head, and mandrels are required when you
use polishing accessories, cutting wheels,
sanding discs, and polishing points. The
reason mandrels are used is that sanding
disc.s, cutting wheels and similar accessories
must be replaced frequently. The mandrel is
a permanent shank, allowing you to replace
only the worm head when necessary, thus
saving the expense of replacing the shaft
each time.

shapes, and are made for intricate work on
ceramics (greenware), wood carvings, jewelry,

virtually every possible kind of grinding
application. Use them for sharpening lawn
mowers blades, screwdriver tips, knives,
scissors, chisets and other cutting tools. Use
to remove flash from metal castings, debur-
ring any metal after cutting, smoothing
welded joints, grinding off rivets and removing
rust. In macnineshops, high soeed drtllsand
cutters normally are ground with aluminum
oxide wheels.
Silcon Carbide Grinding Stones

are made especially for use on hard materials
such as glass and ceramics. Typical uses
might be the removal of stilt marks and

Aluminum Oxide Abrasive Wheels

O
Sanding Accessories
Sanding discs in fine, medium, and coarse
grades are made to fit mandrel No. 402. They
can be used for nearly any small sanding job
you might have, from model making to fine
furniture finishing. In addition, there is the
drum sander, a tiny drum which fits into the
Moto-Tool and makes it possible to shape
wood, smooth fiberglass, sand inside curves
and other difficult places, and other sanding
jobs. You replace the sanding bands on the
drum as they become worn and lose their
grit. Bands come in fine and coarse grades.
Wire Brushes
Three different shapes of wire brushes are
available. For best results wire brushes
should be used at speeds not greater than
15,000 RPM. They remove rust from tools
and other metal surfaces, and clean and
burnish metal parts. Use for such jobs as
cleaning electrical connections to assure
good conduction.
Bristle Brushes
These are excellent cleaning tools on silverware,
jewelry and antiques. The three shapes make
it possible to get into tight corners and other
difficult places. Bristle brushes can be used
with polishing compound for faster cleaning
or polishing.
When using the steel saws
(Nos. 400, 406) or cutoff
wheels (Nos, 409, 420, 426) always have the
work securely clamped. Never attempt to
hold the work with one hand while using
either of these accessories. The reason is
that these wheels will grab if they become
slightly canted in the groove, and can kick-
back causing loss of control resulting in
serious injury. Your second hand should be
used to steady and guide the hand holding
the tool. When a cutoff wheel grabs, the
wheel itself usually breaks. When the steel
saw wheel grabs, it may jump from the
groove and you could lose control of the
tool.
Cutting Wheels
These are thin discs of emery or fiberglass
used for slicing, cutting off and similar
operations. Use them for cutting off frozen
bolt heads and nuts, or to reslot a screw head
which has become so damaged that the
screwdriver won't work in it. Fine for cutting
BX cable, small rods, jubing, cable and
cutting rectangular holes_ln sheet metal.
