Aluminum Oxide Grinding Stones (orange/brown)
Round, pointed, flat — you name the shape and there is
one available in this category. These are made of alu-
minum oxide and cover virtually every possible kind of
grinding application. Use them for sharpening lawn
mower blades, screwdriver tips, knives, scissors, chis-
els and other cutting tools. Use to remove flash from
metal castings, deburring any metal after cutting,
smoothing welded joints, grinding off rivets and remov-
ing rust. In machine shops, high speed drills and cutters
normally are ground with aluminum oxide wheels.
Silicon Carbide Grinding Stones (green/gray)
Tougher than aluminum oxide points, these are made
especially for use on hard materials such as glass and
ceramics. Typical uses might be the removal of stilt
marks and excess glaze on ceramics and engraving on
glass.
Diamond Wheel Points
Excellent for fine detail work on wood, jade, ceramic,
glass and other hard material. Bits are covered with
diamond particles. 3/32" shanks.
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.

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.
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.
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. The three
shapes come in three different materials: stainless
steel, brass and carbon wire. The stainless steel per-
form well on pewter, aluminum, stainless steel, and
other metals, without leaving "after-rust". Brass brush-
es 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.
