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.
Grinding Wheel
Use for deburring, removing rust, and general purpose
grinding. Use with Mandrel #402.
Cutting Wheels
These thin discs of emery or fiberglass are 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, tubing, cable and cutting rectangular holes
in sheet metal.
