08B901 - Walter HP 9-Inch Type 28 Saucer Grinding Wheel for Steel

Industrial Grade Type 28 Abrasive for Heavy Fabrication

The Walter 08B901 HP™ Grinding Wheel is a specialized abrasive tool designed to meet the rigorous demands of industrial steel fabrication and MRO environments. Measuring 9 inches in diameter with a 1/4-inch thickness, this wheel features a distinct Type 28 "saucer" geometry. Unlike standard Type 27 depressed center wheels, the Type 28 profile is engineered to operate at a shallower angle relative to the workpiece, typically between 0 and 15 degrees. This configuration significantly increases the contact area between the abrasive and the metal, facilitating more efficient surface leveling and blending operations.

Part of Walter's High Performance (HP) series, this wheel is formulated with a proprietary bond and high-grade abrasive grains optimized for mild steel. The matrix is designed to resist glazing and loading, ensuring that the wheel maintains a consistent cut rate throughout its lifespan. This durability makes the 08B901 a cost-effective solution for high-volume shops where downtime for wheel changes must be minimized. The wheel's structure is reinforced to withstand the high torque and rotational forces of 9-inch angle grinders, ensuring safety and stability during aggressive material removal tasks.

The ergonomic benefits of the Type 28 shape are substantial for operators performing extended grinding shifts. By allowing the grinder to be held in a more natural, flatter position, the wheel reduces the strain on wrists and forearms often associated with steep-angle grinding. This design is particularly effective for smoothing long weld seams, deburring flame-cut edges, and preparing surfaces for painting or coating. The 08B901 combines aggressive stock removal with operator-centric design, making it a staple in heavy manufacturing, shipbuilding, and structural steel industries.

Technical specifications include a standard arbor fitment compatible with most industrial 9-inch grinders (verify specific arbor size, typically 7/8" or 5/8"-11 hub depending on variant, this SKU represents the wheel only). It is strictly recommended for use on steel applications to maximize performance and prevent cross-contamination if used in mixed-metal environments. For safety, always ensure the grinder's speed rating matches or exceeds the wheel's maximum RPM rating.
