DEWALT DWA8051B15 4-1/2" x .045" Cut-Off Wheels, 7/8" Arbor, 15-Pack

The DEWALT DWA8051B15 General Purpose Cut-Off Wheels give you a dependable 15-wheel supply for everyday angle-grinder work. With a custom blend of aluminum oxide grain and a thin .045" profile, these 4-1/2" bonded abrasive wheels cut through steel and other metals quickly while leaving a cleaner edge that reduces secondary cleanup. They're the go-to choice for metal fabricators, maintenance pros, and serious DIYers who want consistent performance without spending on specialty wheels.

DEWALT DWA8051B15 Cut-Off Wheels: Fast Cuts and Clean Edges

The thin wheel design is a big advantage: it removes less material, cuts faster, and produces less burr, which means less grinding and sanding after the cut. At the same time, each wheel is built with two sheets of fiberglass reinforcement to maintain strength and help reduce wheel breakage on the job. A standard 7/8" arbor fits most 4-1/2" angle grinders, so you can keep a pack on the truck and load a fresh wheel whenever you need it.

Choosing the Right 4-1/2" Cut-Off Wheel for Your Project

The DWA8051B15 is optimized for general-purpose metal cutting. The aluminum oxide grain is a proven choice for steel and stainless steel, and the .045" thickness is a good balance of speed and durability for most shop and jobsite cuts. If you need a thicker wheel for more aggressive grinding, consider a .060" or .090" option; but for clean cut-off work, this thin wheel is hard to beat.

For best results, match the wheel maximum RPM to your grinder's no-load speed, let the wheel do the cutting without forcing it, and always use the proper guard and eye protection.

15 Wheels, One Convenient Pack

With 15 wheels in the pack, you're ready for multiple jobs without constant reordering. The compact arbor design and consistent dimensions from wheel to wheel help maintain accuracy, whether you're cutting rebar, angle iron, or sheet metal.
