Freud DMADS0400 Diamond Segmented Masonry Disc 4 in 5 Pack

Product Description

The FREUD DMADS0400 is a 4-inch diamond segmented cut-off disc engineered for demanding masonry cutting applications. Sold in a 5-pack, these Diablo-branded discs use industrial-grade diamonds bonded to a hardened disc body to deliver consistent cutting quality through hardened materials. The segmented rim design reduces heat buildup during cutting and extends disc life. According to manufacturer data, these discs provide up to 2 times longer cutting life compared to standard diamond cut-off discs. Licensed tradespeople and experienced contractors rely on this disc for high-volume masonry work where disc longevity and cut quality directly affect productivity.

These discs are suited for cutting concrete, concrete with rebar, brick, and cinder block. Typical applications include residential and commercial masonry work such as cutting pavers, block walls, and structural concrete. The 4-inch diameter makes them compatible with small angle grinders and cut-off tools commonly used in tight spaces or detail work on job sites. The hardened disc body maintains structural integrity under continuous load, making these discs appropriate for both occasional fieldwork and high-frequency production cutting environments.

Installation Notes

Installation and use of cut-off discs should be performed by qualified tradespeople familiar with angle grinder safety. Always power down and disconnect the tool before mounting or changing a disc. Inspect each disc for cracks or damage before use and never operate above the rated RPM marked on the disc. Eye protection, hearing protection, and a dust mask rated for silica dust are required when cutting concrete or masonry materials.
