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

Silicon Carbide Grinding Stones
(blue/green)

materials such as glass and ce ramics.

marks and excess glaze on ceramics and
engraving on glass. 1/8" shank.
Diamond Wheel Points

ceramic, glass and other hard material. Bits

Wire Brushes
Maximum
speed 15,000/min. Allow
brush to run at 15,000/min for one minute
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, copper and brass. The
carbon wire brushes are good for general
purpose cleaning.
