Freud DMACW0400 Diamond Cup Wheel 4 Inches Masonry

Product Description

The FREUD DMACW0400 is a 4-inch diamond cup wheel engineered for masonry and concrete grinding applications. Part of the Diablo line, this cup wheel is built with industrial-grade diamonds that deliver lasting cutting performance under demanding jobsite conditions. L-shaped diamond segments reduce gouging and swirl marks on work surfaces, while extra-wide slots channel dust and debris away from the grind zone for improved visibility and cleaner results. Rated for up to 3 times faster material removal compared to standard diamond cup wheels, this tool is suited for trades professionals who need reliable, high-output grinding on concrete, block, and masonry substrates.

The DMACW0400 is designed for use on 4-inch angle grinders in concrete grinding and surface preparation tasks.

This cup wheel is a practical choice for concrete contractors, tile setters, masonry workers, and general construction trades working on both residential and light commercial projects.
