22360 - United Abrasives 22360 A46N Aluminum Cut-Off Wheel, 6" x .045" x 7/8" Type 27 (50-Pack)

Specialized Aluminum Cutting Performance

The United Abrasives/SAIT 22360 A46N Aluminum Cut-Off Wheel is a premium abrasive tool engineered specifically for the unique challenges of working with non-ferrous metals. Standard cutting wheels often fail when applied to aluminum due to the material's low melting point and softness, which causes the metal to adhere to the abrasive grains—a phenomenon known as "loading." This loading glazes over the cutting surface, increasing heat generation and drastically reducing cutting efficiency. The A46N formulation addresses this by utilizing a specialized soft bond and aluminum oxide grain structure that promotes continuous breakdown of the abrasive surface, ensuring that fresh, sharp grain is always exposed and preventing the wheel from clogging.

Structural Integrity and Safety

Safety and durability are paramount in the design of the 22360 wheel. It features a Type 27 depressed center profile, which not only adds rigidity to the wheel for straighter cuts but also allows the locking nut to be recessed, enabling flush cutting against surfaces. The wheel is externally reinforced with high-strength fiberglass layers, providing the structural integrity necessary to withstand the stresses of high-speed rotation (up to 10,200 RPM) and lateral pressure. This reinforcement is critical for thin .045-inch wheels, offering the operator peace of mind while delivering the performance required for industrial applications.

Application Versatility

While optimized for aluminum, the A46N composition is equally effective on other non-ferrous metals such as copper and brass. The .045-inch thickness minimizes kerf width, resulting in less material waste and faster cutting speeds compared to thicker grinding discs. Manufactured in the United States, these wheels adhere to strict quality control standards, ensuring consistent balance and wear rates across every wheel in the 50-pack carton. This product is an essential consumable for fabrication shops dealing with architectural aluminum, automotive components, or marine repair.
