Dewalt Accessories DW4782 Segmented Diamond Blade 4.5 in

Product Description

The DEWALT ACCESSORIES DW4782 is a 4.5-inch segmented diamond blade engineered for fast, efficient dry cutting of concrete, stone, and brick. The blade features a high-performance diamond matrix with large cobalt-infused diamond segments that deliver aggressive material removal and extended service life — rated at 200 times the lifespan of conventional abrasive blades. The laser-welded, heat-treated steel body provides structural resilience under the sustained stress of demanding masonry cuts. This blade is suited for licensed contractors and experienced tradespeople working in masonry, concrete flatwork, and hardscape applications.

The DW4782 is designed for professional masonry cutting tasks in both residential and commercial settings. Typical applications include cutting concrete slabs, block, brick, and natural stone. The segmented rim design promotes airflow and heat dissipation during dry cutting, helping maintain cut quality over extended use. The blade ships in a package of 10 units, making it practical for job-site stocking or crew supply.
