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. Refer to
Operating Speeds section for proper tool speed
setting. The three shapes come in three different
materials: stainless steel, brass and carbon wire. The
stainless steel perform well on pewter, aluminum,
stainless steel, and other metals, without leaving "after-
rust". Brass brushes are non sparking, and softer than
steel; making them good for use on soft metal like
gold, cooper and brass. The carbon wire brushes are
good for general purpose cleaning.
Bristle Brushes
These are excellent cleaning tools on silverware, jew-
elry 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.
Brushing Pressure
1. Remember, the tips of a wire brush do the work.
Operate the brush with the lightest pressure so only
the tips of the wire come in contact with the work.
2. If heavier pressures are used, the wires will be
overstressed, resulting in a wiping action; and if this
is continued, the life of the brush will be shortened
due to wire fatigue.
3. Apply the brush to the work in such a way that as
much of the brush face as possible is in full contact
with the work. Applying the side or edge of the brush
to the work will result in wire breakage and shortened
brush life.
Polishing Accessories
These include an impregnated polishing point and an
impregnated polishing wheel for bringing metal sur-
faces to smooth finish; a felt polishing tip and felt
polishing wheel, and cloth polishing wheel, all used for
polishing plastics, metals, jewelry and small parts. Also
included in this group is a polishing compound (No.
421) for use with the felt and cloth polishers.
Polishing points make a very smooth surface, but a
high luster is obtained using felt or cloth wheels and
polishing compound. For best results polishing
accessories should be used at speeds not greater
than 15,000 RPM.
No polishing compound is needed when using the
425 Polishing Wheel or 427 Polishing point.
Aluminum Oxide Abrasive Wheels
Use to remove paint, deburr metal, polish stainless
steel and other metals. Available in fine and medium
grits. 1/8" shank.
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
Rotary Tool and makes it possible to shape wood,
smooth fiberglass, sand inside curves and other diffi-
cult 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.
Flapwheels grind and polish flat or contoured surfaces.
They are used most effectively as a finishing sander
after heavier surface sanding and material removal is
completed. Flapwheels come in fine and coarse
grades. Buffs are a great finishing accessory for clean-
ing and light sanding. They work effectively on metal,
glass, wood, aluminum and plastics. Coarse and medi-
um buffs are sold together. 1/8" shank.
Grinding Wheel
Use for deburring, removing rust, and general purpose
grinding. Use with Mandrel #402.
