Cut to the
science of
the matter.
3M abrasive technologies.
The precision-shaped grain found in
3M™ Cubitron™ II Abrasives combines
the advanced material properties of our
original Cubitron grain with the precise
microreplicated structures pioneered in
3M™ Trizact™ Abrasives. As the triangular
shaped grain wears, it continuously
fractures to form sharp points and edges.
Conventional ceramic abrasive grain is
irregular and blocky in shape. Instead of a
clean, machining action, the grain tends to
“plow” through the metal, causing heat to
build up in the workpiece and the abrasive —
resulting in a slower cut, shorter belt life and
undesirable eects, such as burnishing.
Shaping a new era of
grinding performance.

The fast yet forgiving cut and consistent
TM
performance of Scotch-Brite™ Abrasives
allows you to improve surfaces without
signicantly changing the shape of
dimension or the workpiece —and helps
prevent undercutting and gouging.
Revolutionary 3M technologies
deliver required geometry
tolerances without sacricing cut
rates on hard-to-grind materials.
Consistently and easily achieve
nishing specs part after part.
Flexible, non-woven construction
with high concentration of active
mineral sites for fast, consistent
cutting without compromising
nal nish. Specially coated
to minimize loading. Produces
controlled, uniform scratch
throughout life of the abrasive.
Trizact
™
Derived from patented 3M microreplication
technology, 3M™ Trizact™ Abrasives consist
of precisely-shaped three-dimensional
structures distributed uniformly over the
substrate. Unlike conventional abrasives,
which are constructed from randomlyspaced and irregular-shaped minerals, the
uniform conguration of Trizact abrasives
helps deliver consistent performance.
Conventional abrasives start
out sharp, but dull quickly.
The three-dimensional structures
of 3M™ Trizact™ Abrasives contain
multiple layers of mineral. As
these structures wear, fresh, sharp
mineral is constantly exposed
to the workpiece, resulting in
faster, more consistent cutting
throughout the life of the belt.

3M™ Cubitron™ II Abrasive Belt 984F
New 3M™ Cubitron™ II Abrasive Belts have raised the bar for
grinding performance and productivity — thanks to a breakthrough
3M technology that re-writes the rules for speed, consistency and
belt life.
• Cuts cooler —diverts heat from the workpiece
and belt to the swarf
• Helps eliminate burnishing and heat stress
• 3M’s highest performing belt in most metal
working applications
3M™ Trizact™ Cloth Belt 363FC
3M’s newest belt for cylindrical and centerless grinding provides outstanding performance
when dimensioning the base material prior to thermal spray coating of parts. Combine
the unmatched consistency of this Trizact abrasive with the ease and versatility of a belt
dimensioning process for fast, predictable results on stainless, mild and hardened steel.
Grade A300 provides quick cutting and accurate dimensioning of base metal prior to thermal
spray coating. Finer nishes can be quickly achieved through simple belt changes to the
appropriate abrasive grade.

grades, shapes and sizes— from 3" cup wheels to 24" centerless
grinding wheels.
3M™ Resin Bond Superabrasive Wheels
3M manufactures a full line of bonded and single layer
superabrasive products utilizing the latest induction and furnace
heating techniques. They provide excellent form retention as well
as abrasion and heat resistance when grinding tough materials
such as carbides, quartz, ceramics and hard metals.
Faster, safer and more cost-eective way
to achieve desired size and nish.
• Consistent and fast-cutting —at rates up
to 25% higher than typical wheels
• Reduced consumables cost —can
eliminate the need for dressing sticks
• Higher productivity — allows increased
feed rates, while reducing or eliminating
the need for wheel conditioning
• Lower maintenance costs — reduces
debris in coolant, minimizing wear
and tear on equipment and reducing
the particle load on the ltration system
• Enhanced worker safety—can avoid the
risks associated with manual sticking
3M™ Trizact™ Diamond Cloth Belt 663FC
3M Trizact Diamond Cloth Belt 663FC represents the next
generation in abrasive technology—combining the predictable
dimensioning traditionally associated with bonded wheels with
the speed, consistency and ease of use of 3M abrasive belts.
663FC belts cut up to 70% faster than typical bonded wheels.
And because they are easy to use, even less-experienced
operators can achieve consistent, eective stock removal
throughout the life of the belt. This also means that lower
grinding forces can be used, minimizing the chance
of deformation, chatter and other grinding defects on
lightweight/thin-walled components.
