08B500 - Walter HP Spin-On Grinding Wheel 5-Inch Type 27S for Steel

High-Performance Grinding for Industrial Steel Applications

The Walter HP Type 27S Spin-On Grinding Wheel (SKU: 08B500) represents a pinnacle in abrasive engineering for heavy-duty steel fabrication. Designed to meet the rigorous demands of industrial environments, this 5-inch wheel features Walter's proprietary HPA formulation, optimized specifically for mild steel and structural steel applications. The wheel is constructed with a coarse 24-grit aluminum oxide blend that excels at rough grinding, snagging, and heavy stock removal, ensuring that operators can remove material quickly and efficiently without excessive heat buildup.

One of the standout features of this product is the integrated Spin-On mounting system. Unlike traditional grinding wheels that require a flange nut and a pin wrench for installation, the Type 27S design incorporates a 5/8"-11 threaded arbor directly into the wheel's hub. This allows for tool-free mounting and dismounting, significantly reducing the time spent on wheel changes. For operations where downtime translates directly to lost revenue, the speed and convenience of the Spin-On system offer a tangible return on investment.

Safety is paramount in abrasive applications, and Walter has engineered the 08B500 with a deeply anchored, wrap-around steel hub. This mechanical locking system provides superior strength and stability compared to standard glued hubs, minimizing the risk of wheel separation even under high-stress conditions. Furthermore, the integrated hub design helps to center the wheel perfectly on the grinder spindle, reducing vibration. Lower vibration levels not only improve operator comfort and reduce fatigue but also contribute to a more consistent finish and reduced wear on the power tool itself.

This wheel is ideal for a wide range of tasks including preparing weld edges, shaping metal parts, and deburring heavy steel components. The 1/4-inch thickness provides the rigidity necessary for aggressive side grinding, while the depressed center (Type 27) profile allows the operator to work at a comfortable 15 to 30-degree angle relative to the workpiece. Whether utilized in a shipyard, a structural steel plant, or a general fabrication shop, the Walter HP Spin-On wheel delivers consistent performance, safety, and speed.
