20070 - SAIT 20070 5-Inch A24N Type 27 Grinding Wheel, 25-Pack

Technical Overview: United Abrasives/SAIT 20070 A24N Grinding Wheel

The United Abrasives/SAIT 20070 is a high-performance Type 27 depressed center grinding wheel designed for aggressive stock removal on ferrous metals. Engineered with a specific A24N formulation, this wheel utilizes a softer bond matrix combined with high-quality aluminum oxide grain. In abrasive technology, a "softer" bond allows the wheel to break down at a controlled rate, constantly exposing fresh, sharp grain to the workpiece. This mechanism significantly increases the rate of material removal compared to harder wheels, making the A24N ideal for applications where speed and throughput are critical priorities.

Structurally, the 20070 wheel is internally reinforced with the highest quality fiberglass mesh. This reinforcement is crucial for maintaining structural integrity under the high centrifugal forces and lateral pressures encountered during angle grinding operations. The wheel measures 5 inches in diameter with a 1/4-inch thickness and a standard 7/8-inch arbor, making it compatible with a wide range of industrial angle grinders. It is rated for a maximum operating speed of 12,200 RPM, ensuring compatibility with standard high-speed grinding equipment.

This product is specifically optimized for use on iron, steel, and welds. The aluminum oxide grain provides a consistent cut, while the manufacturing process ensures uniformity from wheel to wheel. As a Type 27 wheel, it features a depressed center that allows the locking nut to sit flush or below the grinding surface, permitting grinding at flat angles (typically 15 to 30 degrees) without interference. Manufactured in the United States, the SAIT 20070 adheres to strict quality and safety standards, providing industrial operators with a reliable consumable for heavy-duty fabrication and MRO environments.

The 25-pack configuration ensures that high-volume fabrication shops have a steady supply of consumables, reducing downtime associated with restocking. Whether used for beveling, weld leveling, or general surface preparation, the A24N bond offers a balance of speed and performance that professionals demand.
