DEWALT Diamond Blade for Masonry, Dry Cutting, Continuous Rim, 7/8-Inch Arbor, 4-1/2-Inch

This 4-1/2-inch diamond blade from DEWALT provides a dedicated dry-cutting solution for masonry projects. Built with a continuous rim and a 7/8-inch arbor, it gives users a specialized tool designed to cut cleanly through tough masonry materials without requiring water cooling.

The blade features a high-performance diamond matrix engineered to deliver 200 times the operating life of standard abrasive blades. This durable construction also enhances material removal rates, helping you work through tough masonry with less resistance.

Its thinner kerf design plays a major role in day-to-day usability by boosting overall cutting speed. This slim profile also helps minimize dust generation during dry cuts, keeping your workspace cleaner than wider, traditional abrasive wheels.

As a trade-off, this blade is specifically built for dry cutting and fits tools requiring a 7/8-inch arbor, meaning it is not designed for wet applications or tools requiring different mount sizes without appropriate adapters. The listing also does not specify maximum RPM ratings or recommended material thicknesses.

Verdict: This blade is a solid choice for anyone needing a fast-cutting, durable dry-masonry blade with standard 7/8-inch arbor compatibility. It delivers high longevity and reduced dust for everyday masonry cutting tasks.

A great fit if you:

• Need a durable diamond blade for dry-cutting masonry tasks
