Description

The DEWALT DW4784 7-inch High Performance Segmented Diamond Blade brings serious cutting power to masonry, stone, and concrete work. Its high-performance diamond matrix delivers up to 200 times the life of conventional abrasives and removes material quickly. The laser-welded heat-treated steel body increases durability, while large diamond segments with cobalt handle tough jobs with ease. Use it wet or dry for a clean cut in many hard materials.

DEWALT DW4784 Diamond Blade: Built to Last Longer and Cut Faster

This blade’s premium diamond matrix is engineered to stay sharp far longer than abrasive discs. The segmented rim increases airflow to cool the blade during long cuts, and the cobalt-infused segments give it the toughness to push through brick, block, paver, tile, and various stone products. The result is less downtime, less dust, and consistent performance across heavy job sites.

Wet or Dry Cutting Flexibility

Need to switch from dry asphalt cutting to wet tile cutting? The DW4784 can be used in both modes, saving you from owning multiple blades. Just follow the manufacturer’s speed and guard recommendations. A 7-inch diameter fits standard masonry saws and angle grinders with the proper guard and arbor.

Product Details

Segmented vs. Continuous Rim Blades

Segmented blades cut faster and run cooler for dry cutting, while continuous rim blades give smoother, cleaner cuts in tile and stone. This segmented blade is best for concrete, brick, and masonry where speed is a priority.

Wet or Dry Cutting Tips

When cutting dry, make periodic passes and let the blade spin free to cool. When cutting wet, keep water flowing over the cutting zone to reduce dust and extend blade life. Always wear a respirator and eye protection.

Match the Blade to the Material

Using the right blade for the material reduces wear and prevents dangerous kickback. This DW4784 is built for stone, masonry, and concrete products, not steel or wood. Keep separate blades for different materials.

Frequently Asked Questions

Can I use this blade for cutting concrete?

Yes, it is designed for masonry, concrete, and stone. Always use the appropriate guard and follow ratings.

Is it safe for dry cutting?

Yes, the segmented rim is suitable for dry cutting, but allow the blade to cool with periodic open-air rotation and avoid forcing it.

Used it on a DIY patio project. It made clean cuts. I didn't need a new blade after.
