II Abrasive Belts have
set the world standard for cutting
speed and belt life. Now, our expanded
lineup of Cubitron II belts gives you
more choices of grades, sizes and
constructions – so you can enjoy
the same world-class performance
in applications ranging from high
pressure automated grinding to
low and medium pressure offhand
applications.
Cubitron II belts continue to raise
the bar for grinding performance
and productivity – thanks to a
breakthrough 3M technology that
re-writes the rules for speed,
consistency and belt life.
• Average up to 30% faster cutting on
hard-to-grind metals than the next-
best competitive belt
• Cuts cooler – diverts heat from the
workpiece and belt to the swarf
• Helps eliminate burnishing and
heat stress
• Lasts up to 4 times as long as
conventional ceramic aluminum
oxide belts
• Now available in more belt sizes,
grades and constructions, for
applications ranging from high
pressure, automated grinding
to low and medium pressure
offhand operations
Improved Productivity
“With Cubitron II belts, we’ve reduced
belt changeover time by over 50%.”
– Casting House
Shaping a new era
The secret behind the revolutionary performance of new Cubitron II
belts lies in their proprietary triangular-shaped abrasive grain. These self-
sharpening triangles are designed to fracture as they wear, continuously
forming new, super-sharp points and edges that slice cleanly through the
metal like a knife, instead of gouging or plowing. This prevents heat from
building up in the workpiece – reducing heat-related stress cracks and
discoloration. And, because the abrasive itself stays cooler and sharper,
it lasts up to four times as long as conventional ceramic grain belts!
Less Operator Fatigue
“Because Cubitron II belts cut faster,
nearly all operators report that much
less pressure is required throughout
the life of the belt.”

As shown by the
sparks in this photo,
Cubitron II abrasives
divert heat to the
swarf, keeping both
the workpiece and
the belt cooler.
Higher Cut Rates
“It took our operator 60 minutes
to complete a work order using a
competitor’s belt. He completed
the same size work order in just
45 minutes, using a Cubitron II belt.”
– Precision Casting Company
Longer Belt Life
“I was able to get three times the life with
the 994F 36+ versus the competitive
ceramic belt. Not only did this increase
my productivity but it also reduced the
hassle of belt changeover.”

Cuts Cooler, for Improved Part Quality
“We processed 24 parts with no heat
stress using a single Cubitron II belt,
versus a competitive belt that showed
signs of heat stress on the very first part.”
– Investment Casting Company
of grinding performance
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 effects, such as burnishing.
The new precision-shaped grain found
in 3M
™
Cubitron
™
II Belts 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.
The result is a belt that cuts faster, stays
cooler and lasts up to 4 times longer than
the next best competitive belt.

This photo shows four identical 304 stainless steel bars after
nine grinding cycles of ten seconds each. While the three bars
that were ground using conventional ceramic abrasive belts
show varying degrees of oxidation, the bar ground with a
Cubitron II belt is free of burnishing.
This photo shows three identical 304 stainless steel bars after
nine grinding cycles of ten seconds per cycle using equal
pressure. In that time, the Cubitron II belt removed more than
50% more metal than the so-called “next-generation” ceramic
grain abrasive.
Taking productivity to the next level
3M

Cubitron
™
II Belts not only
last up to four times longer
than conventional ceramic
abrasive belts, but also cut
faster throughout their life. This
translates to more finished parts
per belt per hour – and more
profit to your bottom line.
But no belt can live up to its full
potential – unless your employees
see the benefit. That’s where
Cubitron II belts can really push
your productivity over the top.
For example, many operators
report that Cubitron II belts run
smoother, and cut fast with less
pressure. This can mean less
operator fatigue and greater
comfort – which in turn can
lead to fewer errors, greater
consistency and improved
employee morale.

3M surveys indicate that most operators stop using a belt when performance drops
to 2/3 of its initial cut rate. As this graph shows, Cubitron II belts take twice as long
to reach that end point as conventional ceramic abrasive belts. In addition, Cubitron II
belts cut faster throughout their entire life. Bottom line? Not only is more work done
per unit of time, but also much more total work per belt.
