Aluminum Oxide Grinding Stones
(red/brown)
Round, pointed, flat — you name the shape
and there is one available in this category.
These are made of aluminum oxide and
cover virtually every possible kind of grinding
application. Use them for sharpening lawn
mower blades, screwdriver tips, knives,
scissors, chisels and other cutting tools. Use
to remove flash from metal castings,
deburring any metal after cutting, smoothing
welded joints, grinding off rivets and re mov ing
rust. These grinding stones can be resharped
with a dressing stone. In machine shops, high
speed drills and cut ters normally are ground
with aluminum oxide wheels. 1/8" shank.
Silicon Carbide Grinding Stones
(blue/green)
Tougher than aluminum oxide points, these
are made es pecially for use on hard
materials such as glass and ce ramics.
Typical uses might be the removal of stilt
marks and excess glaze on ceramics and
engraving on glass. 1/8" shank.
Diamond Wheel Points
Excellent for fine detail work on wood, jade,
ceramic, glass and other hard material. Bits
are covered with diamond particles. 1/8"
shanks. (Not recommended for drilling)
Wire Brushes
brush to run at 15,000/min for one minute
Maximum operating
speed 15,000/min. Allow
before use. Refer to Operating Speeds
section for proper tool speed setting.
Three different shapes of wire brushes are
available. 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.
INCORRECT:
Excessive pressure can cause wire breakage.
CORRECT: Wire tips doing the work.
