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 eects, such as burnishing.
Shaping a new era of grinding performance.

performance of Scotch-Brite™ Abrasives allows you to improve surfaces without
signicantly changing the shape of
dimension or the workpiece —and helps prevent undercutting and gouging.
Revolutionary 3M technologies deliver required geometry tolerances without sacricing 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 conguration 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.
