DEWALT DW3521 Masonry Abrasive Blade: Fast Cutting for Tough Materials

The DW3521 is engineered to handle the demands of cutting masonry all day. Its premium silicon carbide abrasive promotes fast cutting without glazing over, and the blade's proprietary material mix keeps the wheel working long after cheaper blades dull.

Why Silicon Carbide?

Silicon carbide is harder than traditional aluminum oxide abrasives, which means the blade slices through concrete, stone, and masonry more quickly and stays sharp longer. That translates to less downtime and more productive work on the job site.

Built to Last with Fiberglass Layers

Two full sheets of fiberglass reinforcement give the blade added strength and help contain fragments if the wheel is stressed. This is a key safety feature for high-speed worm drive saws.

Choosing the Right 7-Inch Blade for Your Saw

The DW3521 is a 7-inch diameter blade with a 1/8-inch thickness and a diamond knockout arbor made for worm drive saws. Verify your saw's arbor and blade guard before fitting this blade.

Cutting Tips for Better Results

Let the blade cut at its own pace, avoid forcing the saw, and keep the cutting line straight. Always wear appropriate eye, face, and hearing protection.
