Ingco 125mm (5 Inch) Professional Dry Diamond Cutting Disc - Segmented Rim Concrete and Masonry Blade with 22.2mm Arbor for Angle Grinders (DMD011252)

Slicing through cured concrete, clay roof tiles, structural brickwork, or dense granite with standard abrasive wheels is an expensive and time-consuming struggle. Non-diamond wheels wear down to the nub within minutes, generate choking clouds of dust, and lose their cutting depth rapidly, slowing down high-volume site work. The Ingco DMD011252 125mm (5 Inch) Professional Dry Diamond Cutting Disc is an industrial-grade masonry solution engineered to deliver lightning-fast, deep-set separations without water cooling. Outfitted with an aggressive segmented rim configuration and an optimized 125mm profile, this premium diamond wheel allows construction contractors, bricklayers, and tiling specialists to cut through heavy stone and structural building materials with absolute speed and mechanical control.

The elite cutting speed and immense structural lifespan of this disc stem from its high-concentration synthetic industrial diamond matrix bonded to a premium alloy steel core. The segmented rim design features deep cooling gullets along the edge, which pull air into the cut to rapidly dissipate friction heat, eject stone dust, and prevent the core from warping during extended dry operations. Its standard 22.2mm internal arbor center fits seamlessly onto all popular 5-inch angle grinders, delivering a balanced, low-vibration spin under extreme heavy-duty loading. Specifically engineered to maintain its full structural diameter for its entire working life, this unyielding wheel guarantees a consistent, maximum-depth cut from the first pass to the last.

Key Features

• Industrial Segmented Rim Design – Deep edge segments provide incredibly aggressive cutting action through hard masonry while channeling air to cool the disc natively.

• Premium Diamond Matrix Concentration – Formulated with top-tier industrial diamond grit to ensure exceptionally high wear resistance and a massive working service life.

• Optimized 125mm (5") Framing – The perfect intermediate size balance, offering deeper cutting reach than standard 115mm discs while retaining high agility.

• Advanced Dry Cutting Core – Engineered specifically to handle intense thermal friction without structural failure, eliminating the absolute need for constant water feeding systems.

• Universal 22.2mm Arbor Fitment – Precision-machined center bore drops directly onto standard 5-inch angle grinder spindles, ensuring a completely stable, chatter-free rotation.

• Double-Blister Commercial Pack – Shipped safely enclosed in a heavy-duty, transparent double-blister layout to protect the precision diamond segments from transit impact.
