Equipped with an X weight backing and proprietary 3M microreplication technology, the 3M Trizact Cloth Roll 237AA is specially designed for low to medium pressure applications projects that would benefit from a semi-flexible abrasive with aluminum oxide mineral. Cloth Roll 237AA is commonly used on mild steel, stainless steel, nickel, cobalt alloys, aluminum, brass, copper and titanium.
- Pyramid-like abrasive structures minimize heat build-up that results from dull mineral gouging the substrate
- Pyramid-like structures contain abrasive mineral that cuts cleanly through the substrate, producing finer finishes than conventional abrasives
- Semi-flexible backing for consistent finish over contours
- Ideal for intermediate finishing and fine polishing prior to plating or buffing
- Resin bond helps abrasive withstand heat

PRODUCT FAQ
-
What is the 3M™ Trizact™ Cloth Roll 237AA used for?
The 3M™ Trizact™ Cloth Roll 237AA is designed for precision finishing and polishing of metals, especially in industries like automotive, metal fabrication, and aerospace. It provides consistent, fine finishes on a variety of surfaces!
-
What does "A65" mean in the product description?
“A65” refers to the grade or level of abrasiveness—the higher the number, the finer the finish. A65 is great for medium to fine finishing tasks.
-
How wide and long is this roll?
This roll is 1-1/2 inches wide and 50 yards long—plenty of material to handle even large projects without frequent replacements!
-
Is this cloth roll flexible and easy to work with?
Yes, it is “full-flex,” which means it’s very flexible. That makes it perfect for working on both contoured and flat surfaces.
-
Are there any splices or breaks in the roll?
No worries there—this roll comes in continuous length with no splices at all! That means you get consistent performance from end to end.
The 3M™ Trizact™ Cloth Roll 237AA stands out due to its advanced construction, which leverages 3M’s proprietary microreplication technology. This innovative process encapsulates micron-graded aluminum oxide mineral within precisely engineered, microscopic pyramids. These pyramids are uniformly distributed across a robust X-weight cloth backing, ensuring even mineral placement. Unlike traditional abrasives, which may have inconsistently spaced mineral particles, Trizact abrasives are designed for uniformity and reliability. As the abrasive is used, the pyramids gradually wear down, continuously exposing fresh, sharp mineral surfaces. This results in a consistently high-quality cut and a predictable, fine finish throughout the product’s lifespan. The ongoing sharp cutting action reduces the need for additional abrasive steps, streamlining your workflow and minimizing material waste due to inconsistent results.
X-Weight Backing Balances Conformability and DurabilityThe 3M™ Trizact™ Cloth Roll 237AA is engineered with an X-weight cloth backing, which is recognized for its durability and semi-flexible nature. This heavier backing provides enhanced operator control and is ideal for medium-pressure grinding applications. Additionally, the roll incorporates a specialized grinding aid that activates during use, helping to dissipate heat and prevent issues such as warping, delamination, and discoloration. This feature is particularly valuable when working with heat-sensitive materials, as it helps maintain the integrity and appearance of your workpieces. The X-weight backing strikes an optimal balance between conformability and strength, making it suitable for a wide range of finishing and grinding tasks.
Great VersatilityThe versatility of the 3M™ Trizact™ Cloth Roll 237AA makes it an excellent choice for a variety of applications. The roll can be easily cut and shaped to fit specific project requirements, offering flexibility for different tasks. Available in a comprehensive range of grades from A6 to A160, users can select the ideal grade for their desired finish—where a lower A-grade (such as A6) delivers a finer finish, and a higher A-grade (such as A160) provides a coarser result. Regardless of the grade chosen, operators can expect fast, consistent cutting action and reliable performance, part after part. This makes the 3M™ Trizact™ Cloth Roll 237AA a go-to solution for achieving uniform finishes and improving productivity in both manual and automated processes.
