Wheels
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 signifi cantly changing the
shape or dimension of the workpiece.
• Are well-suited for an array of cleaning, blending, deburring,
fi nishing and polishing applications.
• Help prevent undercutting or gouging through their controlled
abrasive action.
• Provide consistent, uniform fi nishes 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.
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
Selecting Convolute vs. Unitized
This choice will often be determined by the part confi guration,
wheel size availability, tool speed or other fi xed circumstances.
Convolute is a wrapped construction on a standard sized core
and the “fl at” 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.
Basic Performance Differences
Scotch-Brite™ wheels, one of the most complete selections
of surface conditioning wheels, continue to raise the bar for
performance even after fi ve decades.

Convolute / Molded Wheels
Scotch-Brite™ 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).

Scotch-Brite™
Light Deburring Wheel
The Light Deburring Wheel is designed to provide a clean and
economical system for removing fi ne burrs while providing a
highly polished fi nish. Used for fi ne deburring, polishing and
fi nishing because of their conformability, Light Deburring Wheels

Scotch-Brite™
SST Deburring Wheel
Scotch-Brite™
SF Finishing and Deburring Wheel
SST Deburring Wheels are designed for deburring on most
stainless steel, titanium and other demanding alloys. Burrs from
drilling, stamping, punching and other machining operations can
easily be removed with SST wheels.
Unlike some higher density products, SST wheels are somewhat
softer and more conformable, making them ideal for use on more
intricate shapes and contours.
SST wheels are used extensively in the aerospace industry for
deburring and fi nishing parts, and for fi nishing cast and threaded
products used in medical and surgical applications.
The SF Wheel is loaded with mineral that is smear resistant yet
durable when exposed to metal burrs. This results in a wheel
that delivers excellent fi nishes while still handling burrs. In some
applications, this wheel can handle three surface modifying
elements — combining fi nishing, deburring and blending into
one operation.
The SF wheel’s unique resin construction allows it to run
smooth and resist chunking while requiring less frequent
dressing. It is an excellent option when fi nish is critical on
deburring applications.

Scotch-Brite™
Cut and Polish / CPM Wheels
Cut and Polish / CPM Wheels are heavy duty wheels for more
aggressive blending and fi nishing. These long lasting wheels
perform well on tough blending and fi nishing applications such
as removing surface defects, coarse grindlines, blending forging
marks and machining mismatches while leaving a uniform
grain fi nish.
Cut and Polish / CPM Wheels are very similar but have subtle
variations. The CPM Wheel is slightly harder and more aggressive
in demanding applications.
Both wheels can demonstrate value in a variety of applications,
and are especially well suited for centerless fi nishing.

Highly conformable Metal Finishing Wheels are designed to apply
uniform and consistent satin/antique fi nishes. They are used
effectively to blend and match #3 or #4 mill fi nishes on stainless
steel and to create brushed or satin fi nishes on cutlery.
On softer metals such as aluminum, copper and brass, they are
used to blend out minor surface imperfections and handling
marks while providing the desired decorative fi nish.

Scotch-Brite™
Multi-Finishing Wheel
Scotch-Brite™
General Purpose Wheel
Multi-Finishing Wheels are highly conformable, soft wheels that
create uniform and attractive fi nal fi nishes on ferrous and
non-ferrous metals. They are tough enough to fi nish edges and
welds and soft enough to apply a fi nal fi nish on large surfaces.
The load resistant open web construction of these wheels
removes surface contamination and dirt without re-depositing
contaminates onto the work piece. The Silicon Carbide mineral
contained in this wheel offers a unique bright surface that is
often desired by stainless steel fabricators.
General Purpose Wheels offer the greatest selection of grades,
densities and mineral types. They are an excellent starting point
when the application calls for fi ne fi nishing or cleaning.
Like all Scotch-Brite™ products they produce consistent results
and can be easier to use than buffs and compounds and other
fi nishing abrasives.

3M™ XR Metalworking Wheel
The 3M™ XR Metalworking Wheel is loaded with mineral and
is designed for demanding applications such as removing
sharp burrs that may drastically reduce the life of a non-woven
abrasive or rubber bonded wheel.
This wheel retains its shape when dressed, allowing access to
tight areas and right angles. Unlike a bonded wheel, the XR won’t
grab the workpiece, thus requiring less pressure and reducing
operator fatigue. It also includes a grinding aid to increase cut
rate and run cooler.
The combination of 3M’s molded technology and grinding aid
helps the XR last longer, which can help save time and money.

SST Unitized Wheel
SST Unitized Wheels offer the same deburring and fi nishing
advantages as SST Convolute Wheels (SST Deburring Wheels;
refer to page 8). The unitized version of the SST wheel is
recommended when the application requires very narrow widths
and/or small diameter ranges.
SST Unitized Wheels run well on equipment such as bench
motors, fl oor lathes and portable power tools.

Factors Affecting Performance
Product Surface Speed
Because product speed has a significant effect on performance
(cut, life, and finish), it is important to select the proper speed for
a particular operation and work piece.
Generally, low speeds are desired for generating very uniform
satin finishes, for finishing aluminum alloys without lubricants,
and for use on composite or other soft material applications.
High speeds are recommended when it is desired to remove or
blend surface imperfections and tough burrs. This high speed
will result in a faster cut along with finer finishes.
Lubricant–Coolant
Coolants, like water and some water soluble oils, reduce heat
and extend product life while providing a greater cut. In the case
of most oils or tallow lubricants, surface roughness can be
reduced. The higher viscosity lubricants produce lower surface
roughness, i.e., grease produces a finer surface finish than oil. In
automatic or semi-automatic operations, it is desirable to use
lubricants or coolants whenever possible.
Product Hardness (Density)
3M™ Wheels are available in a number of densities or hardnesses.
Generally, the softer products (2, 3, 4, and 5 density) are used for
decorative finishing. They will conform more readily to surface
contours along with generating a more uniform finish. The harder
products (6, 7, 8, and 9 density) are to be used for the more
difficult blending, cleaning and deburring operations.
Recommended Operating Speeds
(SFPM = Surface Feet Per Minute)
Decorative finishing 500–3000 SFPM
Composites/Soft materials 1200–2700 SFPM
Deburring 5000–6500 SFPM
