Freud DMADST0450 4.5 in Diamond Turbo Disc Masonry 5 Pack

Product Description

The FREUD DMADST0450 is a 4.5-inch diamond segmented turbo cut-off disc engineered for demanding masonry cutting applications. Industrial-grade diamonds bonded to a hardened disc body deliver up to 30 percent faster cuts compared to standard diamond cut-off discs. The turbo rim geometry accelerates material removal while maintaining cut quality in hardened substrates. Sold in a 5-pack, these discs are suited for angle grinder use on jobsites where volume cutting across multiple materials is required. Designed for contractors and trade professionals who need consistent performance in concrete, brick, and cinder block work.

These discs are used in residential and commercial masonry work where an angle grinder is the primary cutting tool. Typical applications include scoring and cutting concrete slabs, brick walls, and cinder block. The segmented turbo rim design handles abrasive, high-density materials including concrete with embedded rebar without significant degradation to cut speed or disc life. Demolition, masonry, and concrete flatwork trades are the primary users of this disc type.

Installation Notes

Installation of cut-off discs should be performed by qualified tradespeople familiar with angle grinder safety procedures. Verify the grinder's maximum RPM rating meets or exceeds the disc's rated RPM before mounting. Always inspect the disc for cracks or damage before use and replace the arbor flange if worn. Wear appropriate PPE including eye protection and a dust mask rated for silica-containing materials when cutting masonry or concrete.
