BRUSHING PRESSURE
• 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.
• If heavy pressure is used, wires will be over stressed, resulting
in a wiping action, and if this is continued, the life of the brush will be
shortened due to wire fatigue.
• Apply the work to the face of the brush ensuring as much of the brush
face as possible is in full contact. Applying the work to the side or edge of
the brushing tool will result in wire breakage and shortened brush life.
• Reversing the wheel brush rotation periodically will tend
to increase the life of the brush. This results in the sharpening
of the wire tips or ends, ensuring faster cutting action.

The maximum RPM ratings are
safety ratings not recommended
operating speeds. The optimum
operating speed is determined
by the application and in most
cases lower operating speeds will
prove more efficient and achieve
the best result. As a general guide
we recommend the following
peripheral speeds when working
