Benchmark Abrasives 6" Aluminum Oxide Type 1 Cut Off Wheels, 25-Count

The Benchmark Abrasives 6-Inch Aluminum Oxide Cut Off Wheels are built for metalworkers, fabricators, and DIYers who need clean slicing through various metals. These flat Type 1 discs come in a 25-pack, providing a ready supply for workshop projects involving structural steel, sheet stock, or tubing.

A notable feature of these wheels is the ultra-thin 0.045-inch profile paired with a 6-inch diameter and standard 7/8-inch arbor. This thin kerf removes less material during each pass, helping you achieve precise, burr-free cuts on everything from aluminum and stainless steel to pipes and flat sheets. The aluminum oxide abrasive grain maintains cutting integrity across extended jobs, supporting both direct cutting and light grinding tasks.

For fast production, these wheels are rated for speeds up to 11,000 RPM. This high-speed capability keeps the cut path steady and smooth while reducing vibrations. The 7/8-inch arbor size offers wide compatibility across major power tool brands like Dewalt, Milwaukee, Makita, Bosch, and Metabo, whether you are mounting them to an angle grinder, die grinder, or high-speed saw.

Because these discs are specifically engineered with aluminum oxide for metals like steel and aluminum, they are not designed for masonry or wood cutting. Users should also ensure their power tools can accommodate a 6-inch wheel size and support arbor speeds up to 11,000 RPM.

Verdict: These cut off wheels are an excellent choice for anyone tackling metal fabrication, rail work, or general shop cutting. They offer the right balance of thin-kerf precision, broad tool compatibility, and solid high-speed performance.
