High Speed Cutters
High speed cutters are
used in carving, cutting
and slotting wood, plastics
and soft metals (such as aluminum, copper
and brass). Made of high quality steel.
Structured Tooth Tungsten Carbide Cutters
1/8" shank
These cutters feature fast cutting needle-
sharp teeth for greater material removal with
minimum loading. Use on fiberglass, wood,
plastic, epoxy and rubber.

speeds
15,000 rpm. Refer to Speed Settings
(pages 10-12) for proper tool and setting.
Three different shapes
of wire brushes are
available in three differ-
ent materials: stainless
steel, brass and carbon
wire. Stainless
brushes perform well on pewter, aluminum,
stainless steel and other metals, without
leaving rust. Brass brushes are non-sparking
and softer than steel, making them good for
use on soft metals like gold, copper and
brass. Carbon wire brushes are good for
general purpose cleaning.
Bristle Brushes
Bristle brushes are
used for cleaning tools on
silverware, jewelry and antiques. The three
shapes make it possible to get into tight cor-
ners and other difficult spaces. They can be
used with polishing compound for faster
cleaning or polishing.
Aluminum Oxide Abrasive
Wheels
Used to remove paint, deburr
metal, polish stainless steel
and other metals. Available in
medium grit.

Engraving Cutters
Engraving cutters come in a
wide variety of sizes and
shapes and are used for intricate work on
ceramics (greenware), wood carvings, jewel-
ry and scrimshaw. They are often used in
making complicated printed circuit boards.
They should not be used on steel and very
hard materials, but are good for use on
wood, plastic and soft metals.
Tungsten Carbide Cutters
Tungsten carbide cutters
are long-lived cutters for
use on hardened steel, fired
ceramics and other very hard materials. They
can be used for engraving on tools and gar-
den equipment.
Brushing Pressure
•. The tips of a wire brush do the work.
Operate the brush with the lightest pres-
than
sure so only the tips of the wires come in
contact with the work surface.
•. If heavier pressure is used, the wires will
become overstressed, resulting in a wip-
ing action. If this continues, the life of the
brush will be shortened by fatigue.
•. Apply the brush to the work surface so
the majority of the brush face makes full
contact. Applying the edge or side of the
brush to the work surface will result in
wire breakage and shortened brush life.
Grinding Wheel
Used for deburring, removing
rust, and general purpose grind-
ing. Use with Mandrel #402.
