20082 - SAIT C24N 7-Inch Silicon Carbide Grinding Wheel for Concrete and Cast Iron

Technical Overview of the SAIT 20082 C24N Grinding Wheel

The United Abrasives/SAIT 20082 is a premium-grade abrasive tool engineered specifically for materials that present challenges to standard aluminum oxide wheels. This 7-inch Type 27 grinding wheel utilizes a proprietary Silicon Carbide grain structure. Silicon Carbide (SiC) is harder and sharper than aluminum oxide, making it the abrasive of choice for low tensile strength materials such as concrete, masonry, stone, and cast iron. The grain structure allows for efficient fracturing, ensuring that fresh, sharp cutting edges are continuously exposed during the grinding process.

Designated with the specification C24N, this wheel features a coarse 24-grit composition paired with an 'N' hardness rating. This balance is critical for masonry applications; the bond is soft enough to release worn grain before it glazes over, yet hard enough to provide respectable service life under heavy pressure. The wheel is reinforced with the highest quality fiberglass mesh, providing the structural integrity required to operate safely at speeds up to 8,500 RPM. This reinforcement is essential for resisting the lateral forces often encountered during heavy stock removal operations.

The Type 27 depressed center geometry allows for a wide range of grinding angles, typically between 15 and 30 degrees, making it suitable for smoothing welds on cast iron, leveling concrete surfaces, or shaping stone. Manufactured in the USA, the SAIT 20082 adheres to strict quality control standards, ensuring consistent balance and performance. It is an indispensable consumable for industrial MRO environments where mixed materials—ranging from aggregate to ferrous castings—are processed.

Operators should note that while this wheel is exceptional for cast iron and masonry, it is distinct from standard metal grinding wheels. The specialized chemistry prevents the loading issues often seen when grinding soft or abrasive materials, ensuring the wheel maintains its cutting efficiency throughout its lifespan.
