22380 - SAIT 22380 Ultimate Cut Type 27 Cut-Off Wheel, 4-1/2-Inch x .045 x 7/8 (50-Pack)

Precision Cutting for Professional Welders

Achieve cleaner cuts and reduce prep time with the United Abrasives/SAIT 22380 Ultimate Cut™ wheel. For professional welders, the quality of the cut directly impacts the quality of the fit-up and the final weld. This .045" thin cut-off wheel is designed to slice through metal with surgical precision, leaving a smooth edge that requires minimal secondary grinding or deburring. Its thin profile generates significantly less heat than thicker wheels, preserving the metallurgical properties of heat-sensitive materials like stainless steel and preventing discoloration or warping.

The versatility of the 22380 makes it an essential tool for diverse welding projects. It is rated "Best in Class" for cutting a wide range of materials, including stainless steel, aluminum, copper, brass, and standard carbon steel. The Type 27 (depressed center) design offers added rigidity and allows the locking nut to sit recessed, enabling you to get the wheel closer to the work surface for flush cuts. This is particularly useful when trimming tack welds or cutting material in tight spaces where a flat Type 1 wheel might be obstructed by the grinder's spindle.

United Abrasives manufactures these wheels in the USA using a proprietary grain blend that resists clogging—a common issue when cutting aluminum. The external fiberglass reinforcement ensures the wheel remains stable and safe, even during demanding cuts on thick bar stock or structural tubing. With a 7/8" arbor and a max RPM rating of 13,300, this 50-pack of wheels provides the durability and performance consistency required by professional fabricators who demand the best from their consumables.
