DEWALT DW4523 Type 27 grinding wheel, made with high-performance aluminum oxide grain, offers aggressive stock removal and smooth operation for weld grinding and metal shaping.
Categories : tools
SKU : WOR-TOO-066
The DEWALT DW4523 Type 27 Grinding Wheel is a 4-1/2-inch workhorse for grinding and shaping metal. Its high-performance aluminum oxide grain and dense grain concentration remove material quickly while running smooth, making it a go-to for weld grinding, rust removal, and cleaning up steel and other ferrous materials.
When you need to flatten a weld, knock off spatter, or blend a repair, the DW4523 handles it. The 1/4-inch thickness gives you enough body for aggressive grinding, and the three full sheets of fiberglass reinforcement keep it stable and safe at high speeds.
Always check the arbor size (5/8-inch) and the maximum RPM rating on your angle grinder before mounting.

Using a grinding wheel for cutting puts unnecessary stress on the wheel and can be unsafe. The DW4523 is made for grinding, so keep cutting jobs to a thin cutting disc.
Start at a low angle to flatten the weld bead. Move the wheel in a steady, circular or side-to-side motion. Keep the wheel perpendicular to the surface to avoid gouging.
Always wear eye protection and a face shield. Inspect the wheel before mounting and use the guard. Never exceed the max RPM stamped on the wheel.
Yes, it's designed for aggressive metal grinding, including weld removal and smoothing.
No, it's a Type 27 grinding wheel for surface grinding. For cutting, use a Type 27/41 cutting disc.
It's rated for standard 4-1/2-inch angle grinder speeds. Check the wheel's printed max RPM before use.
Yes, aluminum oxide is suitable for ferrous metals and many non-ferrous materials. It will work on stainless steel with proper technique.
It depends on pressure and material. With normal use, it will last through most weld jobs before needing replacement.






Cuts fast.
Works well on steel, but it wears quick.
I've used these for years. They last a good amount of time. They don't throw sparks everywhere. I buy them in bulk now.
It's a wheel. It grinds.
Made short work of my weld seams. Smooth and didn't vibrate like some cheap wheels.
Good wheel, no complaints.
I'm a metal artist. These give me a clean finish. I go through them fast but that's inevitable. Worth the price.
It works.
Great for the grinder. Removes metal quickly. I'll buy again.
