08B501 - Walter HP 5-Inch Type 28 Spin-On Grinding Wheel for Steel

High-Performance Abrasive for Industrial Steel Fabrication

The Walter HP Type 28 Spin-On Grinding Wheel (SKU: 08B501) represents a significant advancement in abrasive technology for metalworking professionals. Designed specifically for steel applications, this 5-inch by 1/4-inch wheel is engineered to deliver a superior balance of removal rate and wheel life. The "HP" (High Performance) formulation utilizes premium aluminum oxide grain structures bonded with a reinforced resinoid matrix, ensuring that the wheel maintains its aggressive cutting action throughout its lifespan without glazing or premature wear.

One of the defining technical features of this product is its Type 28 "saucer" geometry. Unlike standard Type 27 depressed center wheels, the Type 28 shape is conical, allowing for a flatter angle of attack (typically 15 to 30 degrees). This geometry provides a larger contact area with the workpiece, making it ideal for smoothing surfaces and leveling welds with greater control. The saucer shape also enhances rigidity, which translates to more consistent finishes and improved safety during heavy loading.

Efficiency in MRO and fabrication environments is further maximized by the integrated Spin-On mounting system. This 5/8"-11 threaded hub allows operators to mount and dismount the wheel by hand, eliminating the need for pin wrenches and flange nuts. This not only reduces changeover time but also ensures the wheel is automatically centered, significantly reducing vibration. Less vibration protects the angle grinder's bearings and reduces the risk of White Finger Syndrome (HAVS) for the operator. For industrial facilities prioritizing safety, throughput, and ergonomic performance, the Walter HP Type 28 is a benchmark solution.
