Description

STEEL, STAINLESS AND ALUMINUM: These metal cutting discs for angle grinder work slice carbon steel, stainless and cast iron, and double as an aluminum cutting disc. Run them on pipe, tubing, angle iron, rebar, sheet, threaded rod, and seized bolts on the bench. THIN .045" KERF, FIBERGLASS MESH: A thin cutting wheel takes a narrower bite, so this cutoff wheel cuts faster, wastes less parent material, and drops less heat into the work. Reinforced fiberglass mesh runs through the disc, holding a wheel this thin together under side load. CUTTING ONLY, NOT GRINDING: Cut-off wheels cut on the edge, not the face. Never run a grinder cutting wheel across a surface or use one for weld dressing. For grinding work, mount a BHA Type 27 grinding wheel instead, built with the body and bond for that job. PRECISION-BALANCED, RUNS TRUE: This 4-1/2" Type 27 angle grinder cut-off wheel is built flat and balanced on a concentric arbor, so it spins true with minimal wobble, vibration & chatter for clean, straight cuts; fits any 4.5" grinder with a 7/8" arbor, rated to 13,300 RPM. TRUSTED BY PROS: BHA (formerly Black Hawk Abrasives) is a name welders, fabricators, and metalworkers rely on - delivering consistent quality and dependable performance job after job, backed by real customer support. BHA (formerly Black Hawk Abrasives) is a professional-grade abrasive brand, built on Long Island, New York, since 2015. These 4.5 cut-off wheels for metal are made for the shop where the grinder runs all day and every cut has to land. Each 25-pack holds twenty-five Type 27 depressed center cutting wheels measuring 4 1/2" x .045" x 7/8", rated to 13,300 rpm. Shops standardize on this size, so these cut off wheels 4 1/2 inch fit the grinder already on the bench without a guard change. Cutting wheels 4 1/2 inch, cutoff wheels 4 1/2 inch, and cutting discs 4 1/2 for angle grinder all name the same disc. The .045" kerf is why these cut the way they do. A thin metal cutting wheel moves faster, wastes less parent stock, and drops less heat into the cut. The abrasive is A60 aluminum oxide in a hard resinoid bond, with fiberglass mesh running through each grinder metal cutting disc. That mesh holds a wheel this thin together under side load. Fabricators run these 4.5-inch metal cutting wheels across carbon steel, stainless, and cast iron. As a 4.5 cut-off wheel for metal, it takes structural work, and as a 4.5 cutting disc for angle grinder, it trims sheet and tube. Metal cut off wheels 4 1/2 inch see more bench time than any other size. As an aluminum cut-off wheel, it handles non-ferrous stock without tearing the edge. Welders reach for them on pipe, tubing, angle iron, rebar, and seized bolts. The depressed center clears a standard guard and adds rigidity through the cut. Cutoff wheels cut on the edge. They are not built to grind on the face, and grinder cut off wheels should never be used for surface work. For grinding, BHA makes Type 27 grinding wheels built for it. Fits any 4-1/2 inch angle grinder with a 7/8" arbor. Inspect each wheel before mounting. Always use a guard, protective equipment and proper mounting procedures, as directed in ANSI safety code B7.1 and OSHA.
