Ingco 115mm (4-1/2 Inch) Professional Segmented Diamond Cutting Disc - Heavy-Duty Dry Concrete, Brick, and Masonry Saw Blade for Angle Grinders (DMD071151)

Slicing through high-density aggregate concrete, hard building bricks, or solid masonry blocks using standard abrasive wheels is highly inefficient and expensive. Standard wheels wear down within minutes under heavy structural loads, creating thick clouds of dust while increasing the risk of wheel breakage. The Ingco DMD071151 115mm Professional Segmented Diamond Cutting Disc is an industrial-grade masonry solution engineered for fast, aggressive, and long-lasting cutting performance. Featuring a standard 4-1/2 inch outer diameter footprint, this high-end diamond matrix wheel easily handles deep dry-cutting tasks across heavy renovation and construction job sites.

The exceptional service life and aggressive material removal rate of this disc stem from its high-concentration synthetic diamond grit edge segment matrix. Unlike standard flat blades, the cutting edge features a precision-segmented expansion rim configuration. These deep cooling gullets break up the cutting line to rapidly clear out dense aggregate debris, minimize thermal friction buildup, and allow air to circulate freely through the cut. This specialized engineering prevents the steel core from warping during high-speed dry operations. Outfitted with a standard 22.2mm center arbor, it mounts securely onto commercial 4-1/2" angle grinders, making it the perfect tool for cutting structural walls, chasing electrical channels, and tailoring blockwork.
