20075 - SAIT 20075 5-Inch A24T Type 27 Grinding Wheel

Technical Overview of the SAIT 20075 A24T Grinding Wheel

The United Abrasives/SAIT 20075 is a high-performance Type 27 depressed center grinding wheel engineered for demanding industrial applications. This wheel features an A24T specification, indicating a hard bond formulation paired with coarse aluminum oxide grain. The hard bond is critical for applications involving edge grinding, beveling, and working on rough surfaces where softer wheels would break down prematurely. By maintaining its geometry longer under stress, the A24T series ensures consistent performance and reduces the frequency of wheel changes, thereby optimizing operational efficiency in high-volume fabrication environments.

Structurally, the wheel is internally reinforced with the highest quality fiberglass mesh. This reinforcement is integral to the safety profile of the product, allowing it to withstand the centrifugal forces associated with a maximum speed of 12,200 RPM. The 5-inch diameter and 1/4-inch thickness provide a substantial abrasive surface area and rigidity, making it suitable for heavy stock removal on ferrous metals. The 7/8-inch arbor is compatible with standard industrial angle grinders equipped with a locking nut.

Manufactured in the United States, the SAIT 20075 adheres to strict quality control standards. The uniform grain distribution throughout the wheel ensures that the cutting action remains consistent from the first pass until the wheel is worn down to the stub. This consistency is vital for operators requiring precision and predictability in their grinding operations. The wheel is specifically optimized for ferrous metals, including iron, steel, and heavy welds, making it a staple in structural steel fabrication, shipbuilding, and general MRO applications.

Operators should note that the hard bond, while excellent for longevity on sharp edges, requires appropriate pressure to fracture the grain and maintain cutting action. It is the ideal choice when wheel life and edge retention are the primary metrics of success in the grinding process.
