Freud DMACW0450 Diamond Cup Wheel 4.5in Masonry

Product Description

The FREUD DMACW0450 is a 4.5-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 and L-shaped diamond segments designed to remove material aggressively while minimizing gouging and swirl marks on the work surface. Extra-wide slots run along the face to promote continuous dust extraction during grinding. The result is a wheel that delivers up to three times faster material removal compared to standard diamond cup wheels, with extended service life suited for demanding jobsite conditions. Typically installed by masons, tile setters, and concrete finishing contractors.

This cup wheel is sized at 4.5 inches in diameter and is intended for use in concrete grinding, surface preparation, and masonry work. The extra-wide slot design keeps dust moving away from the cutting surface, which improves visibility and reduces heat buildup during extended use. The L-shaped segment geometry helps maintain a consistent grind pattern without leaving deep swirl marks or gouges, making it appropriate for surface prep work where finish quality matters. It is sold in a package quantity of four wheels.
