wheels, one of the most complete selections
of surface conditioning wheels, continue to raise the bar for
performance even after five decades.
Today, 3M develops wheels with new and advanced technology
while continuously improving its existing product line.
Customers choose Scotch-Brite
™
surface conditioning wheels
because of their ease of use and consistent results. In addition,
to assist in increasing productivity, customers are supported by
dedicated Technical Service teams and 3M Innovation Centers
around the world.
Scotch-Brite

Wheels
• Can improve surfaces without significantly changing the
shape or dimension of the workpiece.
• Are well-suited for an array of cleaning, blending, deburring,
finishing and polishing applications.
• Help prevent undercutting or gouging through their controlled
abrasive action.
• Provide consistent, uniform finishes as fresh abrasives are
continually exposed to the work surface.
• Run cool and resist loading due to their open web
construction, which reduces the risk of part discoloration and
warping, while extending the life of the wheel.
Selecting Convolute vs. Unitized
This choice will often be determined by the part configuration,
wheel size availability, tool speed or other fixed circumstances.
Convolute
is a wrapped construction on a standard sized core
and the “flat” of the web becomes the cutting tool. The wheels
are one directional, which is indicated by an arrow on the side of
the wheel and arrows printed in the core.
Unitized
is a layered construction with a selection of center hole
sizes and no core. The “edge” of the web becomes the cutting
tool. The wheels are non-directional.
See Convolute and Unitized equivalency chart on page 25.
Factors to consider when choosing a
starting point for your application
• Composition of workpiece and material type
• Material hardness
• Desired results to be achieved
• Size and shape of the work piece (area to be conditioned)
• Part variability
• Tool/machinery type, including speed capability
• Previous and possible subsequent abrasive steps

Convolute Wheel performance differences can be attributed to mineral (aggressiveness) and
density (hardness). The combination of these two characteristics and subtle variations determine if the wheel
will cut more aggressively or will be more durable and less conformable (See depiction below).
