22370 - SAIT 22370 7-Inch Type 27 Aluminum Cutting Wheel

United Abrasives SAIT 22370 A46N Aluminum Cut-Off Wheel Overview

The United Abrasives SAIT 22370 is a premium-grade abrasive wheel specifically engineered for the unique challenges of cutting non-ferrous metals. Standard cutting wheels often fail when applied to soft metals like aluminum because the material melts and "loads" or clogs the abrasive grain, rendering the wheel useless and creating dangerous heat buildup. The SAIT A46N formulation addresses this directly with a unique aluminum oxide grain and a soft bond structure. This combination allows the wheel to break down at a controlled rate, constantly exposing fresh, sharp grain to the workpiece while preventing the soft metal from adhering to the wheel face.

Measuring 7 inches in diameter with a thin .045-inch profile, this wheel is designed for speed and precision. The thin kerf removes less material, which translates to faster cuts and less thermal distortion in the workpiece—a critical factor when working with heat-sensitive aluminum alloys. The wheel features a Type 27 depressed center configuration. This geometry is preferred in many industrial applications as it allows the locking nut to sit recessed within the wheel, enabling flush cutting against surfaces and providing the operator with a better line of sight to the cut zone.

Safety and durability are paramount in the design of the 22370. United Abrasives manufactures these wheels in the USA, incorporating external fiberglass reinforcement layers. This reinforcement provides the structural integrity needed to withstand the high rotational forces of angle grinders running up to 8,500 RPM, offering ultimate safety in a thin wheel format. Ideal for fabrication shops, shipyards, and manufacturing facilities processing aluminum, copper, or brass, this wheel delivers consistent, aggressive performance where other wheels falter.
